摘要

•The effect of high stress triaxiality on void nucleation is modeled.•The modeling formulation related to anisotropic critical damage is proposed.•The prediction accuracy of anisotropic ductile fracture is remarkably improved.•It provides a new idea for the construction of anisotropic GTN series model.
