1. Problem Description Why do I get the error Failed to compute elastoplastic strain variables when using plasticity/concrete/soil plasticity? 2. Solution This happens because the elastoplastic element cannot evaluate a plastic step if the current stress state is outside of the yield surface. There are two situations where you may encounter this problem: In the first load step The elastoplastic element fails to evaluate the consistence conditions (due to either loads, displacements, initial stress/strains), and it fails to compute the first elastic-predictor step. That is, your initial state, e.g. assumed in-situ stresses in a geomechanical problem are outside the yield surface. During postprocessing When results are requested at other positions than the Gauss points, the elastoplastic element actually performs a stress computation. If the gradients of the elastoplastic strains are a large within an element this computation may fail. If this happens, use the Gauss point variables such as solid.sGpx instead of general variables like solid.sx. |
