Waves in a fluid-saturated poroelastic matrix composed of two weakly coupled solids,ncluding dissipative effects, a plane wave analysis reveals the existence of three compressional waves and two shear waves. The theory is applied to determine phase velocities of the fast compressional and shear waves in a sample of shaley sandstone, which are shown to fit experimental data.

The meso-scale. Fractures as thin layers in Biot media and induced anisotropy,mples to determine the five complex and frequency dependent stiffnesses characterizing the equivalent TIV medium. These experiments are identified with boundary-value problems which solutions are computed using the finite element procedures.

Modeling Biot media at the meso-scale using a finite element approach,viscoelastic medium having in the average the same attenuation and velocity dispersion than the original highly heterogeneous Biot medium. Each experiment is associated with a boundary-value problem that is solved using the finite element method.

A poroelastic solid saturated by two immiscible fluids, a generalized argument due to the presence of capillary pressure forces. Here capillary forces are included in the wave propagation model using a Lagrange multiplier in the virtual complementary work principle, leading to the derivation of the constitutive relations.
