Original Abstract

The presented paper deals with procedure created for quality and reliability evaluation of duc-tile fracture criteria group. The base for criteria verification is comparison of upsetting experimental results and results of upsetting numerical simulations. Ductile fracture prediction using numerical simu-lation results is compared with experimentally measured ductile fracture. This comparison is also used for evaluation of independence of ductile fracture criteria on stress-strain conditions during different forming processes. There are briefly described upsetting experiments and numerical simulation model created in FEM system ANSYS. Partial results are presented for some ductile fracture criteria
