Cette thèse a pour but de développer un ensemble de méthodes permettant de gérer les problèmes de contact et de couplage de maillages dans le cadre de la méthode des éléments finis classiques et étendus. Ces problèmes d'interfaces sont trai

In this work we develop a set of methods to handle tying and contact problems along real and virtual (embedded) surfaces in the framework of the finite element method. The first objective is to elaborate an efficient and fully consistent three-dimens

We present a unified framework to tie overlapping meshes in solid mechanics applications. This framework is a combination of the X-FEM method and the mortar method, which uses Lagrange multipliers to fulfill the tying constraints. As known, mixed for

A method to treat frictional contact problems along embedded surfaces in the finite element framework is developed. Arbitrarily shaped embedded surfaces, cutting through finite element meshes, are handled by the X-FEM. The frictional contact problem
