Abstract
This paper deals with the antiplane stress state of a uniformly piecewise homogeneous space formed by alternate junction of two distinct layers of the same thickness manufactured of different materials which are weakened by periodic parallel tunnel cracks in their middle planes. The governing system of singular integral equations and the ways of solving the system are are given in general form. The closed solution of the problem is obtained in the special case, where there are central cracks of length 2a in heterogenous layers.
