On the propagation of perturbations along an incompressible elastic medium with multimodulus shear resistance

Under study the features of the propagation of boundary perturbations in the multimodulus incompressible elastic medium with a different resistance to shear stress applied in opposite directions. For the case of plane waves the one-dimensional boundary value problems of a shock shift by the boundary of the halfspace are solved. We show that some piecewise-linear multimodulus incompressible elastic medium nonlinear wave processes (strong and weak breaks, moving as a rigid body layers) can arise.
