Surface Wave Propagation in a Fluid-Saturated Incompressible Porous Layer Lying between an Empty Porous Elastic Layer and an Empty Elastic Porous Half-Space
ABSTRAKT
Dispersion of Rayleigh-type surface waves, in a model consisting of a poroelastic plate of thickness H of a fluid-saturated incompressible porous material lying between an empty porous elastic layer of thickness h and an empty porous half-space, is analyzed. The frequency equation connecting the phase velocity with wave number is derived. Special cases such as (i) Rayleigh-type surface waves in an incompressible poroelastic layer lying between two empty porous elastic half-spaces; (ii) Rayleigh-type surface waves in an incompressible poroelastic layer lying over an elastic half-space; and (iii) Rayleigh waves propagating along the free surface of a fluid-saturated incompressible porous elastic half-space are investigated. Numerical results with graphical presentations of the variations of phase velocity and attenuation coefficient with wave number are also included.
