Abstract

The problem of the steady-state vibrations of an elastic bimaterial consisting of two half-spaces conjugated by a thin soft layer and with a circular torsion crack is solved. The elastic layer is modeled by an interface physical plane with given spring boundary conditions. To solve the problem, the method of boundary integral equation is used. In the low-frequency region of vibrations, the influence of the physical and geometric parameters of the biomaterial and the interlayer on the values of dynamic stress intensity factors in the vicinity of the crack contour is shown.
