摘要：
In this work, an elastic-plastic model with Hill' 48 anisotropic yield surface is coupled with the continuum damage mechanics theory and combined with the bifurcation analysis in order to predict strain localization in thin sheet metals. The resulting approach is implemented into the ABAQUS finite element code within the framework of large strains and plane-stress conditions. A sensitivity analysis with respect to hardening and damage parameters is carried out to identify the most influential parameters on strain localization predictions.
