| We establish some optimal a priori error estimate on some variants of the eXtended Finite Element Method (Xfem), namely the Xfem with a cut-off function and the standard Xfem with a fixed enrichment area. The results are established for the Lame system (homogeneous isotropic elasticity) and the Laplace problem. The convergence of the numerical stress intensity factors is also investigated. We show some numerical experiments which corroborate the theoretical results. |
