| Abstract: | The mechanism of metal ductile fracture was discussed. The general ductility rupture criterion is introduced. Method how to obtain rupture criterion was put forward, and the principle and model of experimentation was described. The successful application of FEM technology was discussed on metal fracture behavior. |
