Subject to an inclined load, we obtain the energy release rate for interface cracks in an isotropic elastic material with various modulus ratios. The energy release rate is calculated by the path independent E-integral using the finite element method with a singular element. In the finite element analysis, we impose avoiding the overlap of the extended crack, which may occur in the large angle kinking. Under the maximum energy release rate criterion, we examine the extension behavior of the interface cracks.
