The temperature fields in two-layer plates under periodic temperature effects on one of the surfaces are considered. The transition to a steady-state temperature field is investigated. For numerical calculations, a program based on the implementation of the finite element method was used. The same steady-state periodic temperature field was obtained asymptotically and was compared with the results of a numerical experiment. Numerical tests showed that for loads close to explosion during detonation of gas mixtures in thermodynamic treatment measures, the periodic temperature field is established after 5-6 cycles of heat flow exposure. Also after analysis of temperature field in single-layer and double-layer plates it is shown that introduction of thermal protection allows to significantly lower temperature of surface under influence of heat flow.
