Popis: Thermoelastic problems are widely investigated for a long time, especially for these materials subject to high temperature and cause apparent variation of stress and strain. The general related researches investigated the internal parameters with known boundary conditions, however, seldom cases investigated the predictions both the boundary thermoelastic values with given internal parameters. This study considers the case of a one-dimensional two-layer composite material with length L. In this paper, we present a methodology with Laplace transformation and the control volume method with the chosen hyperbolic shape function to solve radiation condition in transient coupled thermoelastic problems with two relaxation time constants. As long as the boundary conditions at one end of the material is prescribed, if either the thermal stress or thermal strain at any single point within the material is also known, the thermal stress or thermal strain at other locations can be predicted. For different time constant...
