Abstract: A finite element model previously described is used to analyze indentation of hard-face materials. The materials (substrate and coating) are supposed elastoplastic, the spherical indenter is ...

Abstract: Indentation analysis is performed using a finite element model. The material is supposed elastoplastic, the spherical indenter is elastic. Elastic indentation with friction is first analyzed. It ...

Abstract: A finite element model of hot rolling is described. It is based upon the flow formulation, with a Norton-Hoff purely viscoplastic behavior. We use a steady state approach with free surface ...
