This paper presents an approximation method of path-independent M-integral by mapping of strain and stress fields along the integral path near the crack tip and the synthetic evaluation of kinked or curved crack model in two-dimensional linear fracture mechanics. the proposed M-integral method provides a significant inprovenent in the accuracy of stress intensity factors for static kinked of cufved crack, and in the stability and rate of crack growth for the simulation of fatigue crack.
