摘要

The present paper is concerned with the propagation of plane waves in an isotropic generalized thermoe-lastic solid half-space with two temperatures. The governing equations are modified in the context of the Lord-Shulman theory of generalized thermoelasticity and are solved to show the existence of three plane waves, namely, P, thermal, and SV waves in the x-z plane. The reflection of the P and SV waves from a thermally insulated free surface is studied to obtain the reflection coefficients in closed form. For numerical computations of the speeds and reflection coefficients, a particular material is chosen. The speeds of the plane waves are shown graphically against the two-temperature parameter. The reflection coefficients are also shown graphically against the angle of incidence for different values of the two-temperature parameter.
