Abstract
In this article, the 2D extended finite element method (XFEM) in mode I, was used to model the crack propagation, this use based on modeling by the ABAQUS computer code. The quadratic elements with 4 CPS4R nodes were used to make this modelization. Two examples of meshs with different approximate overall sizes of the mesh one of 0.2 and the other of 0.5 were studied. In addition, the XFEM method was used to know the maximum value of the final crack load of the mesh. The evolution of the strain energy (ALLSE) was studied between the two cases.
