Dear GetFem users,
I have started using Getfem using python. It is powerful!
I am currently running some examples using plasticity. It is calculating a few useful results, including displacement(u) and Von-Mises stresses on nodes. However, for Geomechanics evaluation I need the actual stress tensor (Sigma_ij). I went through the examples. I found demo_tripod_alt calculating the stresses but limited to elastic condition.Please help me with instructions/examples to get stress tensor on nodes for plasticity.
Is there a way use another failure criterion (different to Von-Mises or Tresca), like Mohr-Coulomb?
