Reflection of SV- Waves from the Free Surface of a Magneto-Thermoelastic Isotropic Elastic Half-Space under Initial Stress

Rajneesh Kakar

The aim of this paper is to study the effect of temperature, magnetic field, relaxation time and initial stress on the reflection of plane SV-waves at the free surface of an isotropic elastic half-space under GL-theory. It is found that when SV-wave is incident on the free surface of the above medium, reflected SV-wave, reflected P-wave and a reflected thermal wave is obtained. We find that P-wave is affected due to the presence of thermal and magnetic field whereas SV-wave remains unaffected which is in accordance with the GL-theory since the temperature and magnetic field in an infinite space results only in irrotational changes. The effect of temperature, magnetic field, relaxation time and initial stresses on reflection coefficients of incident SV-wave are plotted under certain practical assumptions.
