摘要：
We solve the problem of the steady-state oscillations of an elastic bimaterial formed by two half spaces connected via a thin compliant interlayer and containing a circular torsion crack. The elastic interlayer is simulated by an interface physical plane with given spring boundary conditions. To solve the problem, we use the method of boundary integral equations. In the low-frequency region of vibrations, we establish the influence of physical and geometric parameters of the bimaterial and the interlayer on the values of the dynamic stress intensity factors in the vicinity of the crack contour.
