Poroelasticity

This book treats the mechanics of porous materials infiltrated with a fluid (poromechanics), focussing on its linear theory (poroelasticity). Porous materials from inanimate bodies such as sand, soil and rock, living bodies such as plant tissue, animal fl

To Nady (Mme M. A. Biot) for her devotion to Dr. M. A. Biot

With Mme Biot in her Bruxelles apartment (2008)

During a visit to Leuven in 2008, I took the photo of the street scene across from the famous Library of Katholieke Universiteit Leuven without knowing that I had accidentally captured the Biot family house from 1924 to 1940 (see arrow). (Compare with Fig. F.1(b))

Preface

Porous materials are found in nature as inanimate objects, such as soils and rocks, in living bodies, such as plants, human flesh, and bones, and as manmade materials, such as polyurethane foams and nanofiltration filters. The pores, or voids, are distributed all over the space the porous body occupies, as cavities, fractures, fissures, vugs, capillary channels, and other interstitial and intergranular spaces. The pores are many, in various shapes and sizes, and are randomly oriented and distributed. For modeling purposes, it is either undesirable, or impossible, to describe their exact geometry and location. As a result, only the averaged, or “homogenized,” material properties and mechanical
