Abstract
The aim of this paper is the investigation of the ductile fracture, which can occur in the formed part during the cold forming processes, in an economical manner. A fracture criterion, based on the McClintock model of void growth and the critical value of plastic strain, is presented to identify the defect locations in the formed part. This criterion is compatible with the results of the rigid-plastic finite element method modelled for simulation of steady and unsteady forming processes on a personal computer (ATARI ST, IBM AT,…). The defect locations can be shown effectively by means of graphic display of such a low-cost computer to compare with the experimentally predicted results.
