A poroelastic model for the effective behavior of granular materials with interface effect

Abstract

Various materials encountered in civil engineering are made up of grains interacting with one another along their interfaces. Their effective mechanical properties are strongly affected by these interfaces, where large local strains are expected. The purpose of the present paper is to derive a linear poroelastic model for fluid-saturated granular media with imperfect interfaces. A new approach based on the definition of an equivalent homogeneous phase is also derived. The latter allows a straightforward analysis of the homogenized behavior of the aforementioned materials.
