摘      要：The Gurson-Tvergaard-Needleman(GTN) damage model was developed basing on anisotropic yield criterion to predict the damage evolution for anisotropic voided ductile *** s quadratic anisotropic yield criterion(1948) and Barlat s 3-component anisotropic yield criterion(1989) were used to describe the anisotropy of the *** defined subroutines were developed using the above *** the benchmark of NUMISHEET 93 square cup deep drawing as an example, the effect of matrix plastic anisotropy on a ductile material was *** predicted result by Barlat 89-GTN model has a better agreement with the experimental data than that by Hill 48-GTN and the original GTN model.
