Re: [Question #665246]: elastic-perfectly plastic material

    Status: Answered => Open

azim is still having a problem:
for some stresses domains  contacts are elastic. when we do load/unload the behavior is linear and returnable. but after a specific stress when we do unloading some strains remain as residual strain, (plastic strain) and the path of unloading differ from the elastic one. 
i want to know the relation between friction angle and stresses with plastic domain???
