Reflection of P and SV waves from free surface of an elastic solid with generalized thermodiffusion

Abstract

The governing equations for generalized thermodiffusion in an elastic solid are solved. There exists three kinds of dilatational waves and a Sheax Vertical (SV) wave in a two-dimensional model of the solid. The reflection phenomena of P and SV waves from free surface of an elastic solid with thermodiffusion is considered. The boundaxy conditions are solved to obtain a system of four non-homogeneous equations for reflection coefficients. These reflection coefficients are found to depend upon the angle of incidence of P and SV waves, thermodiffusion parameters and other material constants. The numerical values of modulus of the reflection coefficients axe presented graphically for different values of thermodiffusion parameters. The dimensional velocities of various plane waves are also computed for different material constants. © Printed in India.
