 note = {In this study, a simple method to determine the complex stress intensity factor of interface crack problem in dissimilar materials is proposed by using the proportional method. This method is based on the fact that the singular stress field near the crack tip is proportional to r^<-0.5> and is controlled by the stress values at the crack tip node calculated by the finite element method. In the present method, the stress intensity factors of interface crack in dissimilar materials are evaluated from the ratio of crack-tip-stress values between a given and a reference problems. A single interface crack in an infinite bi-material plate subjected to tension and shear loads is selected as the reference problem in this study. The accuracy of the present analysis is verified by the comparing the present results with the results obtained by other researches. The calculation shows that the present method gives easily the accurate numerical results for the interface crack problems in dissimilar materials.},
