Abstract
The present work deals with the propagation of Rayleigh surface wave in a self-reinforced thermoelastic layer lying over a dry sandy thermoelastic half-space. The expressions for thermal stresses and displacement components have been derived to characterize the dynamics of dry sandy materials. The dispersion equation of Rayleigh wave is obtained using concepts of potential function subjected to suitable boundary conditions. The obtained dispersion equation is complex in nature, so separating the real part of 6th order determinant expression, the dispersion equation of Rayleigh wave in the earth’s crust of sandy media is obtained and analyzed carefully. Some special cases are deduced to obtain the classical equation of Rayleigh wave that is well-consistent with the pre-established developed outcome. A numerical approach has been taken to express the theoretical result graphically.
