The X-FEM in conjunction with the level set method can be used to simplify the modeling of continua containing several cracks and hence perform effective stress analyses related to fracture mechanics. This paper describes the two-dimensional stress analysis of structures containing cracks. Stress intensity factors having mixed modes coupled with mode-I and mode-II are evaluated by M_1-integral method. This method is examined in numerical examples of elastic analyses. The numerical results show that X-FEM is an effective method for performing stress analyses and evaluating stress intensity factors.
