Abstract: | The governing equations for generalized thermodiffusion in an elastic solid are solved. There exists three kinds of dilatational
waves and a Shear 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 boundary 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 are presented graphically for different values of thermodiffusion parameters. The dimensional
velocities of various plane waves are also computed for different material constants. |
