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

Key words in English

fracture prediction, forming simulation, fracture criteria
