摘要：
In order to define a proper bimaterial stress intensity factor, a general solution for the collinear interface cracks between dissimilar anisotropic media is applied to the near tip of an interface crack. Through the operation of normalization, scaling, nondimensionalization and transformation, a comparable definition which can be reduced to the classical stress intensity factors for a crack tip in homogeneous media has been obtained. For special cases of orthotropic bimaterial interface cracks, the explicit solutions are derived in terms of engineering constants.
