Reflection of SV waves from the free surface of an elastic solid in generalized thermoelastic diffusion

The governing equations for two-dimensional generalized thermoelastic diffusion in an elastic solid are solved. There exist three compressional waves and a shear vertical (SV) wave. The reflection phenomena of SV wave from the free surface of an elastic solid with generalized thermoelastic diffusion is considered. The closed-form expressions for the reflection coefficients for various reflected waves are obtained. These reflection coefficients are found to depend upon the angle of incidence of SV wave, thermoelastic diffusion parameter and other material constants. The numerical values of modulus of the reflection coefficients are presented graphically for different thermal and diffusion parameters.
