Rayleigh waves in a thermo-viscoleastic solid loaded with viscous fluid of varying temperature

In the present paper is concerned with study of thermoelastic interaction in an infinite KelvinVoigt type viscoelastic, thermally conducting solid bordered with viscous liquid half-spaces/layers of varying temperature. Complex secular equations in closed and isolated mathematical conditions for Rayleigh wave propagation in completely separate terms are derived. The results for coupled and uncoupled theories of thermoelasticity have been obtained as particular cases from the derived secular equations. In order to illustrate and compare the theoretical results, the numerical solution is carried out for copper material by using the functional iteration method. The computer simulated results in respect of dispersion curves, attenuation coefficients, amplitudes of temperature change and displacements are presented graphically.
