Hi, how can I enable composite failure criteria in the Field Outputs?
Either Tsai-Wu Criterion or Hashin Criterion. I would like to examine the failure mode in each ply.
I have tried adding *FAILURE CRITERION, TYPE=HASHIN under my material properties but it doesn’t work.
This is not even Abaqus keyword (it should be *DAMAGE INITIATION, CRITERION=HASHIN/TSAIWU or *FAIL STRESS) but CalculiX doesn’t support those criteria anyway. Here’s a full list of the keywords supported by CalculiX: https://www.dhondt.de/ccx_2.22.pdf#page.6
Since there are no such failure criteria in PrePoMax and CalculiX, you could try computing them in postprocessing with the new Create Field Output → Equation tool or in ParaView.
