contact destruction, theory of elasticity, surface wave

The possibility of the existence of surface waves in the range of speeds greater than the speed of shear waves, but smaller than the velocity of longitudinal waves is considered in this paper. The boundary problem for an elastic half-space in this velocity range, there are surface waves, whose velocity is constant and equal to √ 2cS, where cS is the velocity of shear wave. These waves, as well as Rayleigh surface waves have no dispersion. Their speed is determined only by the elastic constants and density of the material. It is shown that the existence of such a speed is possibly related to surface waves in case of constrained deformation. It is possible that they appear as waves of relief in the conditions of straitened deformation.
