✦ Synopsis

The damage process during metal forming is investigated. The coupling of the deformation, thermal and damage processes is taken into account. A linite element program is developed and simple upsetting is simulated. The influence of geometry and friction on rupture is investigated.

In this paper damage propagation during metal forming process is investigated with the concept of continuum damage mechanics, An isotropic damage model based on the theory of materials of type N is adopted to describe the damage process of a ductile material with large elasto-viscoplastic deformatio
