In the present paper, the propagation of surface wave in a generalized thermoelastic solid with voids is considered. The governing equations are solved to obtain the general solution in x-z plane. The appropriate boundary conditions at an interface between two dissimilar half-spaces are satisfied by appropriate particular solutions to obtain the frequency equation of the surface wave in the med...

We consider pseudodifferential Douglis-Nirenberg systems on Rn with components belonging to the standard Hörmander class S∗ 1,δ(R n×Rn), 0 ≤ δ < 1. Parameter-ellipticity with respect to a subsector Λ ⊂ C is introduced and shown to imply the existence of a bounded H∞-calculus in suitable scales of Sobolev, Besov, and Hölder spaces. We also admit non pseudodifferential perturbations. Applications...

Abstract The reflection and refraction due to generalized thermoelastic incident Pand SVwaves at a plane interface between two dissimilar half spaces of visco-thermoelasitic materials have been investigated. Magnitude of coefficient ratios for both the cases of Pand SVwaves have been found out. Several graphs have been drawn to study the nature of variation of the amplitude ratios when the angl...

Abstract The aim of the present paper is to study impact diffusion and impedance parameters on propagation plane waves in a thermoelastic medium for Green Lindsay theory (G-L) Coupled (C-T) thermoelasticity. Results are demonstrated boundary conditions amplitude ratios various reflected against angle incidence calculated numerically. characteristics diffusion, relaxation time impedence paramete...

The current study focuses on one-dimensional (1D) deformation in an excited microelongated semiconductor medium impacted by optoelectronics with exponential laser-pulsed heat. Diffusion effect is considered a photothermal problem of semiconducting media. Microelongated and broad variety concepts have been introduced. Appropriate solutions to set diffusion differential equations found. homogeneo...
