Description
We present a new technique for modelling cracks with frictional contact on crack faces. The extended Finite Element Method (X-FEM) allows one to introduce cracks independently of the mesh. This paper shows how we have adapted a continuous formulation derived from the Augmented Lagrangian Method for contact problems to the X-FEM framework. Numerical examples performed by the Code-Aster illustrate this approach for solving three-dimensional problems with frictional contact. (author)
Abstract (French)
Une nouvelle technique de prise en compte du contact frottant sur les levres des fissures est presentee. La methode X-FEM (eXtended Finite Element Method) permet d'introduire des fissures independamment du maillage considere. Ce papier explique comment nous avons adapte une formulation continue proche du Lagrangien Augmente pour le contact au cadre X-FEM. Des exemples numeriques traites par le Code-Aster viennent illustrer l'emploi de cette approche pour resoudre des problemes tridimensionnels de contact avec frottement. (auteur)Files
