　　A new method is proposed for the numerical evaluation of stress intensity factors(SIFs)for three-dimension(3D)corner crack problems in this paper.Accurate and efficient evaluation of SIFs for 3D corner crack is challengeable.In this work,a direct traction boundary integral equation method(TBIEM)is used to solve these problems.In the TBIEM,the traction boundary integral equation(TBIE)is collocated on both the external boundary and one of the crack surfaces.
