Influence of Biot’s Compressibility Parameters on Transient Response of Saturated Poroelastic Media

In many branches of engineering, the effect of the compressibility parameters of solid and fluid are significant in describing the realistic behavior of porous media. The principle goal of the present work is to clarify the influence of the compressibility of each constituent on consolidation and dynamic behavior of porous media. In this research, an analytical solution in Laplace domain is obtained for dynamic 1-D problem, and further, the response in time domain is evaluated using the convolution quadrature method. By considering a wide range of compressibility parameters, the consolidation and wave propagation behavior are discussed in terms of pore pressure and solid displacement. These results offer some guidance in choosing appropriate compressibility parameters in practical problems.
