A circular element centered at the crack tip is constructed. According to the first four terms of Williams stress function, the displacement pattern with singularity is given to the circular element, where unknown parameters are considered as generalized nodal displacements. On the interface between

With the aid of the basic theorem of the Mellin transform and Fourier series, the general solution of a central crack at the interface between two dissimilar media in a finite disc under longitudinal shear stress is found in this paper. It is of interest to note that the stress intensity factor of t
