摘要：
A contour integral is proposed for the evaluation of stress intensity factors. The integral utilizes the exact solution of a loaded crack in an infinite sheet as an auxiliary solution. The advantage of: this new path-independent integral is that it yields directly the opening mode and sliding mode stress intensity factors. This integral in used together with an indirect boundary element method to calculate stress intensity factors for several cracked configurations.
