Abstract : Acomparison between the exact and approximate secular equation of Rayleigh waves in a Kelvin Voigt viscoelastic plate supported by an orthotropic continuum under initial stress and gravity is studied analytically as well as graphically. The effective boundary condition method is applied to obtain the approximate and exact formulas for the secular equation in a described model. Based on the obtained dispersion equation, the effects of sliding contact on the Rayleigh wave propagation is considered through numerical data. The obtained secular equation is totally explicit and it is a good tool for non destructively evaluating the adhesive bond between the layer and half space as well as their mechanical properties.
