摘要: Most of the phenomenological elastoplastic models adopting a plastic flow rule with single yield surface tend to predict an unrealistic material response especially when they are subjected non-proportional loading condition sudden change path. The work presented in this paper aims propose efficient numerical technique correct excessive stiffness conventional by introducing so-called tangential plasticity [1] and combining it return mapping for accurate faster computation [2].
