Abstract
This paper considers the antiplane stress state of a composite half-space obtained by junction a homogeneous layer and half-space with interphase tunnel cracks and absolutely rigid inclusions, which is deformed by an absolutely rigid die with a plane base acting on the boundary plane of the half-space under the influence of periodically changing loads in time. The governing system of SIE with respect to the amplitudes of the contact stresses acting under the die, the jump of stresses acting on the long sides of the inclusions and the dislocation of the points of the crack edges was obtained. In some particular cases, the method of mechanical quadratures carried out a numerical analysis and revealed patterns of change in stress fields and deformations depending on the physical and mechanical and geometric characteristics of the problem.
