In this paper, a mixed mode interfacial crack in three dimensional bimaterials is analyzed by singular integral equations on the basis of the body force method. In the numerical analysis, unknown body force densities are approximated by the products of the fundamental density functions and power series, where the fundamental density functions are chosen to express a two-dimensional interface crack exactly. The results show that the present method yields smooth variations of mixed mode stress intensity factors of a rectangular interface crack along the crack front accurately. The effect of crack shape on the stress intensity factor for 3D interface cracks is also discussed on the basis of present solution. Then, it is found that the stress intensity factors Ki and Km are always insensitive to the shear modulus ratio, and almost determined by Poisson's ratio alone. Distributions of stress intensity factors are indicated in tables and figures with varying the rectangular shape and Poisson's ratio.
