Metals Overview
The microscale material model is a research code that have been developed outside and used at CAVS for modeling dislocation interactions and reactions in an elastic continuum. The code is used in a hierarchical multiscale framework of the plasticity to obtained information related to the hardening of the material (see for example multiscale framework). Details of the discrete dislocations model can be found in the methodology paper. This particular site contains the research code that has been developed outside for performing and analyzing discrete dislocations simulation results. The research codes used at CAVS comes with a user's manual. We caution the user that there is some risk in using the research version of the codes. For any questions that are not addressed in the user's manual or the 'readme' files accompanying the code, please contact the code developers.
The discrete dislocation simulation code can be used for HCP, BCC and FCC materials.
Material Models
This section includes links to versions of the discrete dislocation dynamics codes. microMegas is commonly used at CAVS to simulate the behavior of dislocations for metals at the microscale.
