Abstract
The mechanics of ductile fracture is complex and not yet fully examined. Depending on the temperature, the rate of deformation and the structure of the metal various mechanisms may be responsible for the softening and fracture. Coalescence of voids, interaction between voids and the external surface of the body, interaction between variously oriented cracks may contribute to the progressing process of ductile fracture. These processes cannot be analysed in terms of the standard fracture mechanics based on the assumption of the elastic model of the material. The model of an elastic-plastic material has been used in numerous works for numerical calculation of the propagation of plastic zones at the front of the crack. On the other hand the possibilities of application of the theory of plastic flow based on the assumption of a rigid plastic model of the material to the analysis of ductile fracture mechanics have been relatively unexplored.
