Abstract

In order to accurately simulate the fine-blanking process, a suitable ductile fracture is significant. So an evaluation strategy based on experimental and corresponding simulation results of tensile, compression, torsion and fine-blanking test is designed to evaluate five typical ductile fracture criteria, which are widely-used in metal forming process. The stress triaxiality and ductile damage of each test specimen are analyzed. The results show that none of these five criteria is sufficient for all tests. Furthermore, an improved fracture criterion based on Rice and Tracey model, taking the influence of both volume change and shape change of voids into account, is proposed. The characterization of this model for fine-blanking process is easily done by the tensile test and the prediction result shows good.
