Reflection of generalized thermoelastic waves from a solid half-space under hydrostatic initial stress

摘要

The basic governing equations for isotropic and homogeneous generalized thermoelastic media under hydorstatic initial stress are formulated in context of Lord–Shulman theory. These governing equations are solved analytically to obtain the dimensional velocities in x–y plane. It is shown that there exists three plane waves, namely, thermal wave, P wave and SV wave. Reflection from insulated stress-free surface is studied to obtain the reflection coefficients of the reflected waves for the incidence of thermal wave. The numerical computations are carried out for a particular model. The Effect of hydrostatic initial stress is observed on these reflected waves.
