Nouvelles approches sans maillage basées sur la méthode des éléments naturels pour la simulation numérique des procédés de mise en forme

Abstract : The finite element method, although employed in the large majority of the industrial codes of simulation, presents a certain number of limitations for the simulation of the processes of working, in particular at the time of great deformations, the localization of the phenomena as it is the case for as it is the case for the formation of bands of shearing or cracks. The need for rebuilding a grid checking a certain number of quality standards involves additional costs of calculation, as well as problems of robustness, particularly for the problems tridimensi
