On the basis of Biot’s dynamic theory of porous media

the response of a cylindrical lined cavity to incident plane-SV-waves was investigated.An analytic solution has been derived for the scattering and diffraction of plane-SV-waves by the lined cavity embedded in a half-space of saturated porous media with the Fourier-Bessel series expansion technique for the first time in this paper.The solution identically applies to the condition when the half-space is degenerated into an elastic medium of single phase

which can be proven by direct comparison of the relevant solutions.Numerical as well as the analytical results have been presented to analyze the effect

of the dimensionless frequency of the incident plane-SV-waves and of the embedded depth of the lined cavity

on the dynamical stress concentration factor over the cavity surface.
