Résumé

The simulation of crack propagation with eXtended Finite Element Method (X-FEM) is proposed. The quenching process induces residual stresses which have an important effect on the in service behavior of mechanical components. In this study, a thick plate is sawed after quenching but this manufacturing step can initiate the propagation of a crack due to residual stresses as observed experimentally. The material is a high yield stress steel whose toughness is low (40CMD8 steel). So, it is very sensitive to brittle fracture phenomena. The aim of this work is to study the crack trajectory after the simulation of the quenching process. The XFEM results are compared with a remeshing technique based on the classical Finite Element Method in 2D.
