“…Reference [29] studied the effect of various parameters like homogeneity, initial stress, wave number, and damping factor on Rayleigh wave propagating in incompressible viscoelastic media. Reference [17] analyzed the impact of the corrugated interface on the phase speed and attenuation of the Rayleigh wave propagating on the surface of micropolar porous half-space lying under a non-viscous liquid layer. Recently, [27] has derived an explicit dispersion equation for the propagation of the Rayleigh wave in an orthotropic medium in the presence of initial stress and gravity and analyzed the effect on velocity and polarization of the Rayleigh wave.…”

The present study signifies the effect of distinct solids on the phase speed and attenuation of Rayleigh surface wave propagating on the boundary of composite porous matrix saturated with fluids. Secular equation depicting propagation of Rayleigh wave is obtained and solved numerically for obtaining phase speed and attenuation coefficient. Two different types of composite materials are considered for numerical study to analyze the effect of solids present in the structure. The study depicts that increase in rigidity of the composite increases the phase speed of the Rayleigh surface wave. Significant effect of the density and bulk modulus of fluid mixture present in the pores is also observed on the phase speed of the wave. The effect of porosity on the phase speed of the Rayleigh wave and the particle motion during the propagation of the wave is also analyzed.
