Poroelasticity and damage theory for saturated cracked media
First, basic results of linear homogenization applied to porous media are presented and applied in order to derive a linear poroelasticity theory for saturated cracked materials. The emphasis is put on the geometrical modelling of the cracks as well as on the cracks-induced anisotropy. The effect of 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.
