Accurate computation of stress intensity factors (SIFs) for two-dimensional cracks by an interaction integral method combined with special crack tip elements is presented in this paper. SIFs are of great importance to fracture mechanics analysis. Due to special variation of displacement around the crack tip and the singularity and near singularity of integrals in interaction integral method, the results obtained by which are affected by the radius of the closed loop. Thus, a general method for singular integrals and nearly singular integrals is...
