Abstract
The dynamic behaviour of metals involves temperature and strain rate effects. In this contribution, two approaches are presented. The first one is based on mecanistical considerations whereas the second one is derived in the classical thermodynamical framework. They both attempt to describe the viscoplastic and damage behaviour of an industrial copper alloy during thin sheet blanking. The numerical results are compared with experimental results. Results from a parametric studies are presented.
