| Abstract: | In this paper,by use of the boundary integral equation method,finite plane crack problem under asymmetric loadings is reduced to solving a set of mixed-type integral equations.The High precision numerical method is also given.To show its reliability and application,we calculated several examples which are useful in engineering practice and obtained their stress intensity factors. |
