REFLECTION OF THERMOELASTIC WAVES AT A SOLID HALF-SPACE WITH TWO RELAXATION TIMES

The effect of two relaxation times, following Green and Lindsay's theory, on the reflection of thermoelastic waves at a homogeneous, isotropic, and thermally conducting elastic solid half-space is studied. The results for the partition of the energy for various values of the angle of incidence are presented and compared with that of Lord and Shulman's theory to show the importance of the second relaxation time.
