Summary:The eXtended Finite Element Method (XFEM) is an innovative approach based on the Finite Element Method (FEM). The XFEM is particularly suited to model crack propagation because of the possibility to include crack growth within solid elements. The present work consisted of a numerical analysis of adhesively-bonded joints with different geometries by the XFEM in Abaqus®, considering different criteria for damage initiation. The XFEM was also validated against experimental results of real tested joints considering different geometries and adhesives. The XFEM analysis revealed that this method is accurate when using the quadratic stress (QUADS) initiation criterion and the triangular propagation law. It was also shown that the joint configuration and respective dimensional parameters, as well as adhesive type, are the most important parameters affecting the joints’ strength.
