Antiplane contact problem for elastic half-space with cracks and stringers

The border of half-space reinforced by stringers. By external forces applied to the plates and the banks of the cracks, the half-space - plate system deformed under antiplane strain. In the frame of well-known Melan model for stringer the solution of the problem is reduced to a system of singular integral equations, whose solution is built by numerically - analytical method of mechanical quadratures. The behavior of the contact stresses and stress intensity factors at the crack tip and the end points of stringers is investigated.
