Abstract
The energy-flux vector connected with the kinetic and internal energy of surface thermoelastic waves is considered. It is shown that this vector is not parallel to the surface of the half-space, as it is in classical elasticity. Its direction at a given point varies with the distance of this point from the surface. Its magnitude decays to 0 when this distance tends to infinity and decays exponentially to 0 in the direction of movement of the straight tine in which the planes of constant phase of the superposed waves intersect the surface of the half-space. Some numerical results are presented when the half space is made of copper and thermally insulated.
