摘要：
In the present article novel approaches to account for localized necking, post-necking and ductile fracture in the numerical simulation of aluminium sheet forming are presented. The modelling concept was implemented in a commercial finite element software and is applied to an aluminium alloy sheet subjected to different forming operations. A validation of the simulation results by means of experiments is employed. It is shown that the proposed modelling framework is capable of accurately predicting the experimental results.
