The propagation of SH wave in a heterogeneous initially stressed viscoelastic layer lying over a heterogeneous initially stressed orthotropic half-space due to a point source is analysed mathematically. The dispersion equation of SH wave is obtained for the propagation of SH wave in a specified model. The method of Green's function and Fourier transformation is incorporated to obtain the dispersion equation. The curves of dispersion equation are sketched for various values of heterogeneous parameters and initial stress on angular frequency, phase velocity and damping velocity in respect of wave number. The dispersion equation is derived for some special cases which reduces to the classical equation of Lovetype wave. The present study reveals the effect of heterogeneous parameter and initial stress associated with both viscoelastic and orthotropic media.

“…mode). Caloi (1948) and Horton (1953) analysed the anelastic characteristics and displacements of the waves considering a Voigt-type dissipation mechanism with small viscous damping and a Poisson solid. Press & Healy (1957) relate the Rayleigh wave quality factor to the body wave quality factors in a low-loss solid, and tested the result successfully with laboratory experiments in Plexiglas.…”

In the surface of a linear viscoelastic medium, two types of Rayleigh waves may propagate. One of them, which always occurs, has wave characteristics which are close to those of the corresponding elastic solid. The second surface wave, not present in the elastic case, is possible for certain values of the material parameters, and for a given range of frequencies. Its properties are different from those of the first surface wave, particularly the energy velocity which is closer to the compressional body wave velocity. In this work, the properties of the two wave modes are analysed by using energy considerations. The energy balance for the Rayleigh waves is computed, and the quality factors and energy velocities are calculated as a function of the frequency, of depth, and per unit surface area.The main results indicate that the anelastic properties calculated from energy considerations are close, for practical purposes, to those obtained from the Rayleigh secular equation, i.e. phase velocity and attenuation factors give a good approximation to the dispersive and dissipation characteristics of the waves. In relation to the elastic case, the energy is more evenly distributed with depth, particularly in the v.e. mode. This wave has similar anelastic properties to those of the compressional body wave.
