Méthodes sans maillage de type éléments naturels pour la simulation des procédés de mise en forme
Keywords:
meshless methods, natural elements, forming processes simulationAbstract
In this paper, numerical simulations of forming processes are presented. A natural neighbor Galerkin method is used. One issue in this technique is the treatment of non-convex domains. To circumvent this problem, two approaches are used, the alpha-NEM and the CNEM. Another difficulty in the NEM is to achieve p-adaptivity. For this purpose, a new Hermite- NEM scheme is proposed to construct higher-order approximation schemes in the NEM.
