Numerical simulation of dynamical fracture in heterogeneous materials

Résumé

A new numerical strategy, based on the coupling between the Cohesive Zone Model (CZM) concept and the Non-Smooth Contact Dynamics (NSCD) approach, for the simulation of the dynamical fracture of heterogeneous materials is presented. The associated software, composed of three libraries with Object Oriented Progam-ming, allows to simulate, in 3D and large deformation, the dynamical fracture of non linear and heterogeneous materials from fracture initiation to post-fracture. The ability of the software, developped by the French "Institut de Radioprotection et de Sûreté Nucléaire" (IRSN) in the frame of its research program on Nuclear Reactor Fuel Safety, is illustrated on the fracture of an heterogeneous material-1 the hydrided Zircaloy-4 constituting standard nuclear cladding tubes-submitted to transient loading.
