Calculation results of different wave tasks are analyzed. It is shown that deformation heating of material is intensive near the boundary surface and quickly decreases during insignificant removal from it. The conclusion is drawn that for obtaining exact solutions of wave tasks in nonisothermal statement it is necessary to consider redistribution of temperature in materials because of the heat transfer and its influence on the intense deformed condition of materials of different designs. Calculation results are given. The sensitivity of the decision to change of specific heat capacity and the thermal diffusivity entering wave equation of heat conductivity is noted.
