Formulation dynamique d'un modèle de zone cohésive tridimensionnel couplant endommagement et frottement

Abstract : We propose in this paper a three-dimensional cohesive zone model, coupling surfacic damage, Coulomb friction and unilateral contact. This model is devoted to the fracture of solids and to the debonding of interfaces. The thermodynamical formulation of the model is given. We focus our attention on the jumps of solution, which could appear with such softening surfacic models. A dynamical formulation allows to overcome these problems of nonsmooth solutions. A particular mathematical and numerical framework is used to solve dynamical problems submitted to unilateral constraints. The ability of the associated numerical tool is underlined on a buckling-driven fracture of a square plate.
