REFLECTION OF PLANE SOUND WAVE FROM A MICROPOLAR GENERALIZED THERMOELASTIC SOLID HALF-SPACE

The present study is concerned with the reflection and refraction of plane sound wave at an interface between a liquid half-space and a micropolar generalized thermoelastic solid half-space. The numerical results are calculated in terms of amplitude ratios for water/aluminium-epoxy composite model for L-S (Lord and Shulman) and G-L (Green and Lindsay) theories. The comparison between these theories reveals the effect of second thermal relaxation time taken by Green and Lindsay. The results are also compared with those without thermal effect.
