Over the 15 last years, several numerical methods have been devised to make the simulation of crack propagation be more and more convenient, flexible, and easy to implement. Among them, the eXtended Finite Element Method (X-FEM [1]) has allowed a significant step in this direction. With only a few additional degrees of freedom (DOF), it is possible to use meshes that do not conform to the crack shape, and so there is no need to remesh the structure at every propagation step. The introduction of… CONTINUE READING
