Extended finite element method (XFEM) is a versatile tool for fracture mechanics. Due to its excellent property, XFEM is widely used in research and engineering. On the other hand, cohesive element is a good option for interface delamination in composite materials. In order to take advantage of these two methods, combined XFEM and cohesive element method is developed for fracture analysis in composite materials in two-dimension. In this method, XFEM is used to simulate matrix fracture, and cohesive element is used to simulate delamination between layers. Due to the differences in the construction of these two methods, special attention is paid to the intersection of these two methods. The new method is applied to the fracture analysis of composite materials. The results show this method has excellent property as expected. This method shows potential application in fracture analysis of composite materials.

ABSTRACT In this paper, a method is proposed for extracting fracture parameters in isotropic material cracking via a stable generalized/extended finite element method. The numerical results of the stress intensity factors and scaled condition number of the system matrix are presented and compared with different enrichment schemes or those reported in related references. The good agreement and convergence of the results obtained by the developed method with those obtained by other solutions or enrichment schemes proves the applicability of the proposed approach and confirms its capability of efficiently extracting fracture parameters in isotropic materials.
