Consider a dynamic equations of thermoelasticity of a uniform isotropic material, which even at small strains are nonlinear. It is shown that such a system can form a stationary nonlinear wave profile, which is a shock wave deformation - drop ("step") of lower value for more. Results and analysis of the exact analytical solution of the problem, describing the shock wave, defined range of parameters under which such a wave can exist.
