The problem of a crack perpendicular to the interface between two different orthotropic composite materials is investigated in this paper.The displacement and the solution of stress field form crack tip are given by using Fourier integral transform.By introducing auxiliary function and using the corresponding boundary conditions,the problem is transformed into the first category containing Cauchy nuclear singular integral equation and the specific method is given.
