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 fo

Semi-physikalisches Stickoxid-Modell, interactions between cracks and the role of the spatial distribution of cracks on the poroelastic properties are also analyzed. The non linear poroelastic behavior of cracked media due to the progressive cracks closure is also investigated. The last section is devoted to damage induced by crack propagation.
