Abstract (EN): A variety of numerical analysis has been carried out by Finite Element Method (FEM), and Extended FEM (XFEM) on Semi-circular Bend (SCB) specimens to evaluate its material behavior, in particular fracture characterization. This work concentrates on calculating stress intensity factor (SIF) assuming an elastic brittle behavior. In order to obtain the required variable fields, FEM formulation was extended to the linear elastic fracture mechanics (LEFM) for the plane stress status. The problem is solved using standard FEM formulation in ABAQUS (c) to obtain the numerical solution of SIFs, the results are compared to the previous work available in the literature. An acceptable agreement was accomplished leading to verify the proposed computational methodology.
