We present the solution of the problem of initial process zone under the conditions of plane deformation in the vicinity of an angular point on the interface of two dissimilar elastic materials playing the role of the origin of an interface crack. We study the dependences of orientation, length, and crack opening displacement on the external load, opening angle of the interface, and the elastic parameters of the joined materials. The conditions of crack initiation are analyzed by using the deformation criterion.
