Application to the determination of the tortuosity and the permeability of cracked materials. -- Microporomechanics -- Poroelasticity and strength of fully or partially saturated porous materials -- Poroelasticity and damage theory for saturated cracked media -- Modeling of Plastic Deformation of Saturated Porous Materials: Effective Stress Concept -- Materials Applications -- Experimental Microporomechanics -- Microelasticity of Bone.Poromechanics is the mechanics of porous materials and is now a well established field in many engineering disciplines, ranging from Civil Engineering, Geophysics, Petroleum Engineering to Bioengineering. However, a rigorous approach that links the physics of the phenomena at stake in porous materials and the macroscopic behaviour is still missing. This book presents such an approach by means of homogenization techniques. Rigorously founded in various theories of micromechanics, these up scaling techniques are developed for the homogenization of transport properties, stiffness and strength properties of porous materials. The special feature of this book is the balance between theory and application, providing the reader with a comprehensive introduction to state-of-the-art homogenization theories and applications to a large range of real life porous materials: concrete, rocks, shales, bones, etc.
