Predictive capacity of selected group of ductile fracture criteria, used in metal forming processes, is evaluated in this study. The method used is based on comparison of upsetting tests that were conducted until first fracture, and their numerical simulation. The aim is to analyse the reliability of various criteria in different conditions, characterised by different stress and strain history. Results of the analysed criteria are presented and the successful ones are then applied to the process of cold forming of bolts.
