<div>[[Frank Read Source Operation|< Frank-Read Source Operation]]<br />
=MDDP Supplemental Notes=<br />
1. The first portion of the MDDP section aims at introducing the basic procedure to run a dislocation dynamics simulation using the code MDDP and its supporting routine, FCCdata. This will be done in the context of an elementary problem involving dislocation multiplication from a dislocation segment pinned at both ends, commonly referred to as Frank Read source (FRS). <br><br />
2. The second part of the homework is an exercise of multiscale modeling; more specifically, upscale bridging of dislocation mobility from the nanoscale to the microscale. The validity of the results of dislocation dynamics simulations hinges on the validity of the mobility law used. The mobility describes the lattice resistance to dislocation glide which is a complex phenomenon involving different mechanisms like phonon and electron drag and is very dependent on the details of core structure as well as temperature and pressure. Because of that, molecular dynamics is the framework most suited to capture mobility, which can then be passed on as one of the centerpieces of the dislocation dynamics calculations.<br />
==Part 1. Frank read source operation==<br />
===Description of the simulation===<br />
The simulation box for our example is 12000b x 12000b x 12000b (in units of the magnitude of the Burgers vector, b, with the origin in the center of the box. The crystal is oriented so that the normal to the (111) plane is along the global z-axis, the [-211] crystallographic direction along the x-axis and the [0-11] along the y-direction. The initial dislocation structure consists of a dislocation line of length 2000b extending along the x-axis with its line sense in the negative x-direction. Its Burgers vector points in the negative y-direction. This makes the character of this dislocation pure edge. Shear stress yz is applied with constant shear strain rate of 10 s-1. The two end points of the dislocation are pinned. The boundary condition is rigid walls in all directions, which means that the dislocations cannot penetrate the walls and would pile-up against it. Under the effect of the shear stress, the dislocation bows out, forms a loop and continuous operating in this mode generating increased number of loops. This process becomes harder as more dislocations pile up against the walls and induce back stress on the source, ultimately shutting it down.<br />
===Running the simulation===<br />
This simulation is performed using MDDP and requires two input files DDinput and data. DDinput features the details of the initial dislocation structure (coordinates, global Burgers’ vector components, slip plane, node constrains, and connectivity of the dislocation nodes), the loading parameters and the mesh size and the time step. The data file includes the material parameters and additional numerical and output control parameter. Please refer to the manual for more details. <br><br />
1. Create a directory and include in it the executable version of MDDP08 (you can use either the Windows MDDP08 executable or the Linux executable) as well as the two input files DDinput and data. The file’s name should be precisely DDinput and data. <br><br />
2. From the command line, execute the program by typing MDDP08.exe (Windows) or ./MDDP08 (Linux) and hit Return <br><br />
3. Respond by y to start the calculations <br><br />
4. The screen output , in order is: <br><br />
Step number, current number of node, total strain, stress, dislocation density, current time step, and load stepping time increment <br><br />
5. The calculations will run until the maximum step numbers is met. In our case you can stop the run when sufficient dislocation activity occurs to demonstrate the operation of the FRS and the hardening effect. <br><br />
===Post processing - visualization of the dislocation structure===<br />
TecPlot is a general postprocessor which offers enhanced capabilities and can read output data from different software. The output files from MDDP are configured to be ready used with TecPlot. The information describing the dislocation structure is dumped into a chain of files starting with “tech” followed by a series number of the file (tech002, tech004, etc.). Each file has the dislocation structure data for 500 time steps. The first 500 steps are written to tech002, the next 500 steps are written to tech004, and so on. This is done in order to keep the files’ size reasonable. A video tutorial can be found [https://www.youtube.com/watch?v=xvplRkBESiM here]. To visualize the dislocation structure, open TecPlot and follow these steps: <br><br />
* From File-->Load Data Files ‐‐ change Files of type: to TecPlot Data Loader and browse for the directory in which you ran the executable<br />
* In the File name: box type te* and hit enter<br />
* The folder should populate with files from tech002 to techIJK (where IJK is the final number of tech files generated)<br />
* Select all of the files you wish to load, and click Open<br />
* Under Plot change XY Line to 3D Cartesian<br />
* From the Plot drop menu, select Axis and from the Axis Details box, check the Show Axis box to show all axes; uncheck Preserve length when changing range, and change the Min: and Max: values for each axis to -6000 and 6000, respectively; click Close<br />
* Under Plot go to Vectorvariableschoose V1, V2, and V3 for U, V, and W respectively. Then go to VectorLength and make sure that the Relative Grid Units/Magnitudes set to 1.0 by going to and click Close<br />
* Click Zone Style... select all of the zones and uncheck Show Zone; Click on Zone 001 and check Show Zone<br />
* On the left hand side of the screen, check the box next to Vector. You should be able to see the initial dislocation lines and use the typical controls to rotate, zoom, etc. to help you visualize the structure<br />
* To visualize the structure at different time steps, under DataEdit Time Strands... Select Constant Delta and ensure that Delta: is set to 1; Click Apply (For a large amount of zones this will take somewhere between 10 minutes and 1 hour to animate)<br />
* An area for animation playback should appear with play, step forward, and go to end blue- colored buttons; you should now be able to play the animation\<br />
* You can modify the speed of playback by clicking Details... next to Solution time:<br />
￼<br />
<br />
===Post processing- XY plot of time histories and stress-strain curves===<br />
￼The main file that contains this information is DDtimeResults.out, which plots the history of multiple variables including the dislocation density, stress, strain, etc. Each plot is referred to as a map in TecPlot. Open TecPlot and follow these steps:<br />
* From File-->Load Data Files ‐‐ change Files of type: to TecPlot Data Loader and browse for the directory in which you ran the executable<br />
* In the File name: box type DD* and hit enter<br />
* Choose DDtimeResults.out and click Open<br />
* The initial XY plot will be a disDensity vs. timenow; you can change this by clicking Mapping Style...<br />
* In the Mapping Style window you will have several map numbers with corresponding names and the variables they are plotted against<br />
* To create the stress-strain curve for your DDtimeResults.out uncheck Show Map for disDens... and check Stress; Right-click on 1:timenow to change the x-axis variable to 4:Strain<br />
* From the Plot drop menu, select Axis and from the Axis Details box, click Reset Range and select Reset to Nice Values; select Y1 at the top and repeat the previous procedure; click Close<br />
* You can now repeat the entire process to produce other curves such as dislocation density vs. stress or strain<br />
==Part 2: Bridging mobility from molecular dynamics to dislocation dynamics==<br />
===Description of the simulation===<br />
The data and DDinput files provided in the MFRS folder represent a simulation box of size 2000b x 2000b x 10000b along the x-, y-, and z-direction, respectively, and containing an initial dislocation structure consisting of 12 Frank Read sources distributed randomly on all slip systems.<br />
===Simulation information===<br />
* Follow the same process as instructed in Part 1 for running the simulation and visualizing the data output.<br />
* For the axis sizes you should change them to match the simulation box size generated by the MFRS DDinput file (2000 x 2000 x 10000).<br />
* Note that since there are 12 FRS the simulation may need to run for more steps than in Part 1, and the output will be larger.<br />

<br />
MDDP simulations can run for calibration of data upscaled from atomistic scale calculations. It is run from an executable and requires two input files. For example, for modeling crystal plasticity in aluminum, the code MDDP can be used to calibrate values of dislocation mobility determined from molecular dynamics simulations. Stress-strain curve data can then be used to upscale to the mesoscale crystal plasticity length scale <ref> [http://dx.doi.org/10.1002/9781118342664 Horstemeyer, Mark F.

<br />
The intermediate strain rate test is initiated by a piezoelectrically controlled actuator. This actuator consists a double action hydraulic cylinder, piezoelectric stack actuator, friction pads, and a bolt to apply preload. The piezoelectric stack actuator expands as a voltage is applied. When the piezoelectric element’s expansion is restricted, it applies a force. The force created by the piezoelectric element is in the normal direction to the friction pads. The friction pads restrict the motion of an extension of the hydraulic cylinder’s piston. This breaking force allows for more energy to be stored in the hydraulic cylinder. When the test is initiated, the voltage is removed from the piezoelectric element. This allows for the energy stored in the hydraulic cylinder to be released; thus, the hydraulic cylinder piston moves in the intended direction to perform a tension or compression test. The maximum force that can be applied to a specimen is 60 kN in the direction of motion. The maximum stroke length of the hydraulic cylinder is 55 mm. Interchangeable grips are used on the end of the extension of the hydraulic cylinder to hold the specimen during the test.<br />

<br />
When an intermediate strain rate test is performed, the stress experienced in the test specimen is transmitted to the serpentine bar in the form of a stress wave. This stress wave travels the length of the transmitted bar and is measured by a strain gauge. Challenges arise with gathering data via the strain gauge. The stress wave created when the test is initiated hits the end of the transmitted bar and is reflected back to the strain gauge before the specimen fails. Therefore, the transmitted bar needs to be as long enough to avoid seeing the reflected wave before the specimen fails. Many national labs and research facilities do not have the footprint available to house a long bar. The original patented design of the serpentine bar features three concentric tubes welded together at the ends. This design allows for the stress wave to propagate through all of the tubes before it reflects back. Therefore, the serpentine bar has an effective length much greater than its physical length creating a more efficient footprint.<br />

<div>==Background in Intermediate Strain Rate Testing==<br />
The intermediate strain rate regime (5 /s to 500 /s) is a relatively uncharted field in mechanical testing. This is despite many phenomena in everyday occurrences happening within this regime. Car accidents, metal forming, and sporting collisions are just a few of the many examples of these. The main reason for this lack of research is due to the lack of technology able to accurately gather this data. Most intermediate strain rate tests are currently performed on Hopkinson bars with a very long transmitted bar. The length of this bar directly impacts the maximum length of the specimen as well as the minimum speed the specimen can be tested. Intermediate strain rate testing also mandates high accelerations to achieve desired speeds during testing. Some machines use a modified servo-hydraulic actuator with a slack adapter in order to allow for more time to reach testing speeds. Although this can drive intermediate strain rate tests, this methodology can require multiple iterative calibration tests to find the correct stand off distance for testing.<br />

=== Overview ===<br />
<br />
As shown on the periodic table of elements, the majority of the chemical elements in pure form are classified as metals. Physical properties show that metals are good electrical conductors and heat conductors, and exhibit good ductility and strength. Shown in chemical properties, metals usually have 1-3 electrons in their outer shell, and loose their valence electrons easily. <br />
<br />
Metals are composed of atoms held together by strong, delocalized bonds called metallic bonding: arrangement of positive ions surrounded by a cloud of delocalized electrons. Above their melting point, metals are liquids, and their atoms are randomly arranged and relatively free to move. However, when cooled below their melting point (solidification), metals rearrange to form ordered, crystalline structures. The smallest repeating array of atoms in a crystal is called a unit cell. In a unit cell, atoms are packed together as closely as possible to form the strongest metallic bonds. Typical packing or stacking arrangements are: face-centered cubic (FCC), body-centered cubic (BCC), and hexagonal close packing (HCP). <br />
As atoms of a melted metal begin to pack together to form a crystal lattice at the freezing point, groups of these atoms form tiny crystals. These tiny crystals increase in size by the progressive addition of atoms. The resulting solid is not one crystal but actually many smaller crystals, called grains. These grains grow until they impinge upon adjacent growing crystals. The interface formed between them is called a grain boundary. Metallic crystals are not perfect. Sometimes there are empty spaces called vacancies, where an atom is missing. Another common defect in metals are dislocations, which are lines of defective bonding. These and other imperfections, as well as the existence of grains and grain boundaries, determine many of the mechanical properties of metals. When a stress is applied to a metal, dislocations are generated and move, allowing the metal to deform.<br />
<br />
When loads (stresses) are applied to metals they deform. If the load is small, metals experience elastic deformation, which involves temporary stretching or bending of bonds between atoms. When higher stresses are applied, permanent (plastic) deformation occurs. This plastic deformation involves the breaking of bonds, often by the motion of dislocations. If placed under too large of a stress, metals will mechanically fail, or fracture. The most common reason for metal failure is fatigue, i.e., a fracture process resulting from the application and release of small stresses and re-application of the load (as many as millions of times).<br />
<br />
In industry, molten metal is cooled to form the solid ([[Casting|casting]]). The solid metal is then thermomechanically shaped to form a particular product. Processes such as extrusion and sheet forming are used for this purpose. During this shaping process, the application of heat and plastic deformation can strongly affect the mechanical properties of a metal. Heat treating induces microstructure changes, such as grain growth, that modify the properties of some metals. Annealing is a softening process in which metals are heated and then allowed to cool slowly. Most steels may be hardened by heating and quenching (cooling rapidly). Quenching produces a metal that is very hard but also brittle. Because plastic deformation results from the movement of dislocations, metals can be strengthened by preventing this motion. When a metal is shaped, dislocations are generated and move. As the number of dislocations in the crystal increases, they will get tangled or pinned and will not be able to move. This will strengthen the metal. This process is known as cold working. At higher temperatures the dislocations can rearrange, so little strengthening occurs. Heating removes the effects of cold-working. When cold worked metals are heated, recrystallization occurs, a process where new grains form and grow to consume the cold worked portion. The new grains have fewer dislocations and the original properties are restored.<br />
<br />
At CAVS at Mississippi State University, we perform research and application work for metals in two branches of materials - lightweight materials of magnesium and aluminum, and steel materials. The material research around these two branches is broad enough to attract various funding sources, from federal agencies to local manufaturers. We form interdisciplinary teams to support the material research. The team includes physicists, chemists, material scientists, mechancial/aerospace/civil engineers to develop multiscale material length scale models for use that are validated using a wide range of [[Equipment|experimental equipment]].<br />

<br />
=== Overview ===<br />
<br />
As shown on the periodic table of elements, the majority of the chemical elements in pure form are classified as metals. Physical properties show that metals are good electrical conductors and heat conductors, and exhibit good ductility and strength. Shown in chemical properties, metals usually have 1-3 electrons in their outer shell, and loose their valence electrons easily. <br />
<br />
Metals are composed of atoms held together by strong, delocalized bonds called metallic bonding: arrangement of positive ions surrounded by a cloud of delocalized electrons. Above their melting point, metals are liquids, and their atoms are randomly arranged and relatively free to move. However, when cooled below their melting point (solidification), metals rearrange to form ordered, crystalline structures. The smallest repeating array of atoms in a crystal is called a unit cell. In a unit cell, atoms are packed together as closely as possible to form the strongest metallic bonds. Typical packing or stacking arrangements are: face-centered cubic (FCC), body-centered cubic (BCC), and hexagonal close packing (HCP). <br />
As atoms of a melted metal begin to pack together to form a crystal lattice at the freezing point, groups of these atoms form tiny crystals. These tiny crystals increase in size by the progressive addition of atoms. The resulting solid is not one crystal but actually many smaller crystals, called grains. These grains grow until they impinge upon adjacent growing crystals. The interface formed between them is called a grain boundary. Metallic crystals are not perfect. Sometimes there are empty spaces called vacancies, where an atom is missing. Another common defect in metals are dislocations, which are lines of defective bonding. These and other imperfections, as well as the existence of grains and grain boundaries, determine many of the mechanical properties of metals. When a stress is applied to a metal, dislocations are generated and move, allowing the metal to deform.<br />
<br />
When loads (stresses) are applied to metals they deform. If the load is small, metals experience elastic deformation, which involves temporary stretching or bending of bonds between atoms. When higher stresses are applied, permanent (plastic) deformation occurs. This plastic deformation involves the breaking of bonds, often by the motion of dislocations. If placed under too large of a stress, metals will mechanically fail, or fracture. The most common reason for metal failure is fatigue, i.e., a fracture process resulting from the application and release of small stresses and re-application of the load (as many as millions of times).<br />
<br />
In industry, molten metal is cooled to form the solid ([[Casting|casting]]). The solid metal is then thermomechanically shaped to form a particular product. Processes such as extrusion and sheet forming are used for this purpose. During this shaping process, the application of heat and plastic deformation can strongly affect the mechanical properties of a metal. Heat treating induces microstructure changes, such as grain growth, that modify the properties of some metals. Annealing is a softening process in which metals are heated and then allowed to cool slowly. Most steels may be hardened by heating and quenching (cooling rapidly). Quenching produces a metal that is very hard but also brittle. Because plastic deformation results from the movement of dislocations, metals can be strengthened by preventing this motion. When a metal is shaped, dislocations are generated and move. As the number of dislocations in the crystal increases, they will get tangled or pinned and will not be able to move. This will strengthen the metal. This process is known as cold working. At higher temperatures the dislocations can rearrange, so little strengthening occurs. Heating removes the effects of cold-working. When cold worked metals are heated, recrystallization occurs, a process where new grains form and grow to consume the cold worked portion. The new grains have fewer dislocations and the original properties are restored.<br />
<br />
At CAVS at Mississippi State University, we perform research and application work for metals in two branches of materials - lightweight materials of magnesium and aluminum, and steel materials. The material research around these two branches is broad enough to attract various funding sources, from federal agencies to local manufaturers. We form interdisciplinary teams to support the material research. The team includes physicists, chemists, material scientists, mechancial/aerospace/civil engineers to develop multiscale material length scale models for use that are validated using a wide range of [[Equipment|experimental equipment]].<br />

=== Overview ===<br />
<br />
As shown on the periodic table of elements, the majority of the chemical elements in pure form are classified as metals. Physical properties show that metals are good electrical conductors and heat conductors, and exhibit good ductility and strength. Shown in chemical properties, metals usually have 1-3 electrons in their outer shell, and loose their valence electrons easily. <br />
<br />
Metals are composed of atoms held together by strong, delocalized bonds called metallic bonding: arrangement of positive ions surrounded by a cloud of delocalized electrons. Above their melting point, metals are liquids, and their atoms are randomly arranged and relatively free to move. However, when cooled below their melting point (solidification), metals rearrange to form ordered, crystalline structures. The smallest repeating array of atoms in a crystal is called a unit cell. In a unit cell, atoms are packed together as closely as possible to form the strongest metallic bonds. Typical packing or stacking arrangements are: face-centered cubic (FCC), body-centered cubic (BCC), and hexagonal close packing (HCP). <br />
As atoms of a melted metal begin to pack together to form a crystal lattice at the freezing point, groups of these atoms form tiny crystals. These tiny crystals increase in size by the progressive addition of atoms. The resulting solid is not one crystal but actually many smaller crystals, called grains. These grains grow until they impinge upon adjacent growing crystals. The interface formed between them is called a grain boundary. Metallic crystals are not perfect. Sometimes there are empty spaces called vacancies, where an atom is missing. Another common defect in metals are dislocations, which are lines of defective bonding. These and other imperfections, as well as the existence of grains and grain boundaries, determine many of the mechanical properties of metals. When a stress is applied to a metal, dislocations are generated and move, allowing the metal to deform.<br />
<br />
When loads (stresses) are applied to metals they deform. If the load is small, metals experience elastic deformation, which involves temporary stretching or bending of bonds between atoms. When higher stresses are applied, permanent (plastic) deformation occurs. This plastic deformation involves the breaking of bonds, often by the motion of dislocations. If placed under too large of a stress, metals will mechanically fail, or fracture. The most common reason for metal failure is fatigue, i.e., a fracture process resulting from the application and release of small stresses and re-application of the load (as many as millions of times).<br />
<br />
In industry, molten metal is cooled to form the solid ([[Casting|casting]]). The solid metal is then thermomechanically shaped to form a particular product. Processes such as extrusion and sheet forming are used for this purpose. During this shaping process, the application of heat and plastic deformation can strongly affect the mechanical properties of a metal. Heat treating induces microstructure changes, such as grain growth, that modify the properties of some metals. Annealing is a softening process in which metals are heated and then allowed to cool slowly. Most steels may be hardened by heating and quenching (cooling rapidly). Quenching produces a metal that is very hard but also brittle. Because plastic deformation results from the movement of dislocations, metals can be strengthened by preventing this motion. When a metal is shaped, dislocations are generated and move. As the number of dislocations in the crystal increases, they will get tangled or pinned and will not be able to move. This will strengthen the metal. This process is known as cold working. At higher temperatures the dislocations can rearrange, so little strengthening occurs. Heating removes the effects of cold-working. When cold worked metals are heated, recrystallization occurs, a process where new grains form and grow to consume the cold worked portion. The new grains have fewer dislocations and the original properties are restored.<br />
<br />
At CAVS at Mississippi State University, we perform research and application work for metals in two branches of materials - lightweight materials of magnesium and aluminum, and steel materials. The material research around these two branches is broad enough to attract various funding sources, from federal agencies to local manufaturers. We form interdisciplinary teams to support the material research. The team includes physicists, chemists, material scientists, mechancial/aerospace/civil engineers to develop multiscale material length scale models for use that are validated using a wide range of [[Equipment|experimental equipment]].<br />

=== Overview ===<br />
<br />
As shown on the periodic table of elements, the majority of the chemical elements in pure form are classified as metals. Physical properties show that metals are good electrical conductors and heat conductors, and exhibit good ductility and strength. Shown in chemical properties, metals usually have 1-3 electrons in their outer shell, and loose their valence electrons easily. <br />
<br />
Metals are composed of atoms held together by strong, delocalized bonds called metallic bonding: arrangement of positive ions surrounded by a cloud of delocalized electrons. Above their melting point, metals are liquids, and their atoms are randomly arranged and relatively free to move. However, when cooled below their melting point (solidification), metals rearrange to form ordered, crystalline structures. The smallest repeating array of atoms in a crystal is called a unit cell. In a unit cell, atoms are packed together as closely as possible to form the strongest metallic bonds. Typical packing or stacking arrangements are: face-centered cubic (FCC), body-centered cubic (BCC), and hexagonal close packing (HCP). <br />
As atoms of a melted metal begin to pack together to form a crystal lattice at the freezing point, groups of these atoms form tiny crystals. These tiny crystals increase in size by the progressive addition of atoms. The resulting solid is not one crystal but actually many smaller crystals, called grains. These grains grow until they impinge upon adjacent growing crystals. The interface formed between them is called a grain boundary. Metallic crystals are not perfect. Sometimes there are empty spaces called vacancies, where an atom is missing. Another common defect in metals are dislocations, which are lines of defective bonding. These and other imperfections, as well as the existence of grains and grain boundaries, determine many of the mechanical properties of metals. When a stress is applied to a metal, dislocations are generated and move, allowing the metal to deform.<br />
<br />
When loads (stresses) are applied to metals they deform. If the load is small, metals experience elastic deformation, which involves temporary stretching or bending of bonds between atoms. When higher stresses are applied, permanent (plastic) deformation occurs. This plastic deformation involves the breaking of bonds, often by the motion of dislocations. If placed under too large of a stress, metals will mechanically fail, or fracture. The most common reason for metal failure is fatigue, i.e., a fracture process resulting from the application and release of small stresses and re-application of the load (as many as millions of times).<br />
<br />
In industry, molten metal is cooled to form the solid ([[Casting|casting]]). The solid metal is then thermomechanically shaped to form a particular product. Processes such as extrusion and sheet forming are used for this purpose. During this shaping process, the application of heat and plastic deformation can strongly affect the mechanical properties of a metal. Heat treating induces microstructure changes, such as grain growth, that modify the properties of some metals. Annealing is a softening process in which metals are heated and then allowed to cool slowly. Most steels may be hardened by heating and quenching (cooling rapidly). Quenching produces a metal that is very hard but also brittle. Because plastic deformation results from the movement of dislocations, metals can be strengthened by preventing this motion. When a metal is shaped, dislocations are generated and move. As the number of dislocations in the crystal increases, they will get tangled or pinned and will not be able to move. This will strengthen the metal. This process is known as cold working. At higher temperatures the dislocations can rearrange, so little strengthening occurs. Heating removes the effects of cold-working. When cold worked metals are heated, recrystallization occurs, a process where new grains form and grow to consume the cold worked portion. The new grains have fewer dislocations and the original properties are restored.<br />
<br />
At CAVS at Mississippi State University, we perform research and application work for metals in two branches of materials - lightweight materials of magnesium and aluminum, and steel materials. The material research around these two branches is broad enough to attract various funding sources, from federal agencies to local manufaturers. We form interdisciplinary teams to support the material research. The team includes physicists, chemists, material scientists, mechancial/aerospace/civil engineers to develop multiscale material length scale models for use that are validated using a wide range of [[Equipment|experimental equipment]].<br />

=== Overview ===<br />
<br />
As shown on the periodic table of elements, the majority of the chemical elements in pure form are classified as metals. Physical properties show that metals are good electrical conductors and heat conductors, and exhibit good ductility and strength. Shown in chemical properties, metals usually have 1-3 electrons in their outer shell, and loose their valence electrons easily. <br />
<br />
Metals are composed of atoms held together by strong, delocalized bonds called metallic bonding: arrangement of positive ions surrounded by a cloud of delocalized electrons. Above their melting point, metals are liquids, and their atoms are randomly arranged and relatively free to move. However, when cooled below their melting point (solidification), metals rearrange to form ordered, crystalline structures. The smallest repeating array of atoms in a crystal is called a unit cell. In a unit cell, atoms are packed together as closely as possible to form the strongest metallic bonds. Typical packing or stacking arrangements are: face-centered cubic (FCC), body-centered cubic (BCC), and hexagonal close packing (HCP). <br />
As atoms of a melted metal begin to pack together to form a crystal lattice at the freezing point, groups of these atoms form tiny crystals. These tiny crystals increase in size by the progressive addition of atoms. The resulting solid is not one crystal but actually many smaller crystals, called grains. These grains grow until they impinge upon adjacent growing crystals. The interface formed between them is called a grain boundary. Metallic crystals are not perfect. Sometimes there are empty spaces called vacancies, where an atom is missing. Another common defect in metals are dislocations, which are lines of defective bonding. These and other imperfections, as well as the existence of grains and grain boundaries, determine many of the mechanical properties of metals. When a stress is applied to a metal, dislocations are generated and move, allowing the metal to deform.<br />
<br />
When loads (stresses) are applied to metals they deform. If the load is small, metals experience elastic deformation, which involves temporary stretching or bending of bonds between atoms. When higher stresses are applied, permanent (plastic) deformation occurs. This plastic deformation involves the breaking of bonds, often by the motion of dislocations. If placed under too large of a stress, metals will mechanically fail, or fracture. The most common reason for metal failure is fatigue, i.e., a fracture process resulting from the application and release of small stresses and re-application of the load (as many as millions of times).<br />
<br />
In industry, molten metal is cooled to form the solid ([[Casting|casting]]). The solid metal is then thermomechanically shaped to form a particular product. Processes such as extrusion and sheet forming are used for this purpose. During this shaping process, the application of heat and plastic deformation can strongly affect the mechanical properties of a metal. Heat treating induces microstructure changes, such as grain growth, that modify the properties of some metals. Annealing is a softening process in which metals are heated and then allowed to cool slowly. Most steels may be hardened by heating and quenching (cooling rapidly). Quenching produces a metal that is very hard but also brittle. Because plastic deformation results from the movement of dislocations, metals can be strengthened by preventing this motion. When a metal is shaped, dislocations are generated and move. As the number of dislocations in the crystal increases, they will get tangled or pinned and will not be able to move. This will strengthen the metal. This process is known as cold working. At higher temperatures the dislocations can rearrange, so little strengthening occurs. Heating removes the effects of cold-working. When cold worked metals are heated, recrystallization occurs, a process where new grains form and grow to consume the cold worked portion. The new grains have fewer dislocations and the original properties are restored.<br />
<br />
At CAVS at Mississippi State University, we perform research and application work for metals in two branches of materials - lightweight materials of magnesium and aluminum, and steel materials. The material research around these two branches is broad enough to attract various funding sources, from federal agencies to local manufaturers. We form interdisciplinary teams to support the material research. The team includes physicists, chemists, material scientists, mechancial/aerospace/civil engineers to develop multiscale material length scale models for use that are validated using a wide range of [[Equipment|experimental equipment]].<br />

<br />
The intermediate strain rate test is initiated by a piezoelectrically controlled actuator. This actuator consists a double action hydraulic cylinder, piezoelectric stack actuator, friction pads, and a bolt to apply preload. The piezoelectric stack actuator expands as a voltage is applied. When the piezoelectric element’s expansion is restricted, it applies a force. The force created by the piezoelectric element is in the normal direction to the friction pads. The friction pads restrict the motion of an extension of the hydraulic cylinder’s piston. This breaking force allows for more energy to be stored in the hydraulic cylinder. When the test is initiated, the voltage is removed from the piezoelectric element. This allows for the energy stored in the hydraulic cylinder to be released; thus, the hydraulic cylinder piston moves in the intended direction to perform a tension or compression test. The maximum force that can be applied to a specimen is 60 kN in the direction of motion. The maximum stroke length of the hydraulic cylinder is 55 mm. Interchangeable grips are used on the end of the extension of the hydraulic cylinder to hold the specimen during the test.</div>Maddoxhttps://icme.hpc.msstate.edu/mediawiki/index.php/Serpentine_Transmitted_BarSerpentine Transmitted Bar2019-04-19T00:53:50Z<p>Maddox: </p>

<br />
[[Intermediate Strain Rate Bar| < Intermediate Strain Rate Bar]] <br><br />
<br />
When an intermediate strain rate test is performed, the stress experienced in the test specimen is transmitted to the serpentine bar in the form of a stress wave. This stress wave travels the length of the transmitted bar and is measured by a strain gauge. Challenges arise with gathering data via the strain gauge. The stress wave created when the test is initiated hits the end of the transmitted bar and is reflected back to the strain gauge before the specimen fails. Therefore, the transmitted bar needs to be as long enough to avoid seeing the reflected wave before the specimen fails. Many national labs and research facilities do not have the footprint available to house a long bar. The original patented design of the serpentine bar features three concentric tubes welded together at the ends. This design allows for the stress wave to propagate through all of the tubes before it reflects back. Therefore, the serpentine bar has an effective length much greater than its physical length creating a more efficient footprint.<br />

<br />
The intermediate strain rate test is initiated by a piezoelectrically controlled actuator. This actuator consists a double action hydraulic cylinder, piezoelectric stack actuator, friction pads, and a bolt to apply preload. The piezoelectric stack actuator expands as a voltage is applied. When the piezoelectric element’s expansion is restricted, it applies a force. The force created by the piezoelectric element is in the normal direction to the friction pads. The friction pads clamp to an extension of the hydraulic cylinder’s piston. This breaking force allows for more energy to be stored in the hydraulic cylinder. When the test is initiated, the voltage is removed from the piezoelectric element. This allows for the energy stored in the hydraulic cylinder to be released; thus, the hydraulic cylinder piston moves in the intended direction to perform a tension or compression test.</div>Maddoxhttps://icme.hpc.msstate.edu/mediawiki/index.php/Serpentine_Transmitted_BarSerpentine Transmitted Bar2019-04-18T06:15:52Z<p>Maddox: </p>

[[Intermediate Strain Rate Bar| < Intermediate Strain Rate Bar]] <br><br />
<br />
When an intermediate strain rate test is performed, the stress experienced in the test specimen is transmitted to the serpentine bar in the form of a stress wave. This stress wave travels the length of the transmitted bar and is measured by a strain gauge. Challenges arise with gathering data via the strain gauge. The stress wave created when the test is initiated hits the end of the transmitted bar and is reflected back to the strain gauge before the specimen fails. Therefore, the transmitted bar needs to be as long enough to avoid seeing the reflected wave before the specimen fails. Many national labs and research facilities do not have the footprint available to house a long bar. The original patented design of the serpentine bar features three concentric tubes welded together at the ends. This design allows for the stress wave to propagate through all of the tubes before it reflects back. This allows for the serpentine bar to have an effective length much greater than its physical length thereby being more efficient for its footprint.<br />
