Objectives

  • Run a multigrain crystal plasticity single finite element simulation.
  • Calibrate macroscale BCJ Plasticity Internal State Variable (ISV) model
  • Run 1 element finite element calculation.
  • Validate Results.

Preparations

Step 1

  • Follow the guide from homework 3 for a single grain crystal plasticity finite element simulation.
  • Alter the inputs for 180 grains with random Euler angles.

Step 2

  • Use the MSU Plasticity-Damage (DMG) model calibration tool to fit a stress-strain curve from crystal plasticity as demonstrated in class.
  • Save the parameters.

Step 3

  • Visit the Macroscale page and collect the user material (UMAT) and ABAQUS input file for aluminum in tension (implicit).
  • Save these files into a new working directory.

Step 4

  • Alter the ABAQUS input file with the parameters calibrated to the DMG model.

Running the Calculation

Step 1

  • Open permissions on files
    chmod 755*

Step 2

  • Enter the following software setup command in a terminal:
    swsetup abaqus

Step 3

  • Submit the abaqus job either locally or to Raptor using the following command:
    abaqus job=NAME_OF_INPUT user=NAME_OF_UMAT
  • Do not include the file extension (.inp) in the "NAME_OF_INPUT".
