A boundary integral formulation is developed to analyze the stress-strain state of an infinite bimaterial containing circular cracks under static torsional loading. A thin flexible layer acts as an interface between the two half-spaces. By applying non-classical contact conditions at the interface, the problem is reduced to a system of 2D boundary integral equations of the Newtonian potential type. These equations are formulated relative to the unknown shear displacement functions on the defect surfaces. By applying non-classical contact conditions at the interface, the problem is reduced to a system of two-dimensional boundary integral equations of the Newtonian potential type. These equations are solved for the unknown shear displacement functions of the defect surfaces.
