โœฆ Synopsis

The material coefficients of Biot's anisotropic poroelasticity are interpreted following micromeehanieal considerations. The adoption of the micro-homogeneity and micro-isotropy assumptions leads to a most practical model for laboratory measurement: the material is defined within 21 drained elastic constants Mijkl, a solid grain bulk modulus Ks, and a Biot modulus M. To facilitate engineering applications, relations among Hookean, engineering and micromechanical constitutive constants are explicitly and extensively listed. These relations are used to convert a set of anisotropic data measured in traditional engineering tests under undrained condition to various continuum mechanical constants.

Using an asymptotic homogenization method, the e!ect of the porous medium microstructure on the values of poroelastic coe$cients is studied in this paper. First, the Biot's poroelasticity theory and general relations linking the macroscopic poroelastic coe$cients with the averaged micromechanical so
