ABSTRACT

The present article deals with the characteristics of Rayleigh wave propagation in thermo- orthotropic half-space. This thermodynamical analysis is carried out in the context of a three-phase-lag thermoelasticity model with two-temperature theory. A more general form of the dispersion equation is derived. The path of surface particles is found to be elliptical during the propagation of Rayleigh waves in a thermoelastic-orthotropic medium. The effect of phase lags on the various components of Rayleigh waves are demonstrated graphically. Finally, it is found that the results obtained in the present problem agree with the results obtained by various other researchers.
