Reflection and refraction of a plane thermoelastic wave at a solid–solid interface under perfect boundary condition, in presence of normal initial stress

Using the basic governing equations for isotropic and homogeneous generalized thermo elastic media under initial stress, the reflection and refraction of thermo elastic plane waves at the interface of two dissimilar thermo elastic solid half-spaces has been investigated. The amplitude ratios of various reflected and refracted waves are obtained for an ideal boundary for the incidence of SV-wave. The numerical computations are carried out for a particular model. The effect of initial stress on the amplitude ratios are shown graphically after numerical calculation.
