SubscriberIf you have a solution, please help me.Â
Model conditionÂ
・Static nonlinear analysis.
・The simple cube is being tensile and compression.Â
Problem
・I evaluated EPPL EQV (vM plastic strain), but that reduced while unloading and compression.Â
・But plastic strain would be accumlation value. -

SubscriberAs the plastic strain increments, it is accumulated in NL:EPEQ. This is the accumulated equivalent plastic strain, which is a scalar measure and always monotonically increasing. If you take the difference between two substeps, you are getting the incremental equivalent plastic strain.
