Abstract :
[en] In this paper, we present a general consistent numerical formulation able to take into account strain rate and thermal effects of the material behavior. A thermomechanical implicit approach for element erosion to model material failure is also presented. The numerical model will be illustrated by applications both from the metal forming and the impact domain. All these physical phenomena have been included in an implicit dynamic oriented object finite element code (implemented at LTAS-MN2L, University of Liège, Belgium) named Metafor [http://www.ltas-mnl.ulg.ac.be/dokuwiki doku.php?id=metafor:start].
