Description

Files:

  • ConfigStiffnessDegradation.py: The main python script which should be run through Abaqus
  • utilities.py and LaminateModel.py: Python function definition used by the Config...py script
  • OA2D.f: Main user-element (UEL) used in Abaqus
  • koutvar.inc.f : Common block definition used by the shadowing element for contour plot output from OA2D.f
  • SubConfig: batch-script used in order to run the script on a linux-cluster using batch (content depends on cluster setup)

The codes are used in the following publication to where reference should be made:
