Modélisation du comportement mécanique des argilites de l'Est
The aim of this work is to propose a poroplastic damage model, in according to experimental results, for claystone (Aublivé-Conil, 2003). Firstly, an anisotropic elastoplastic damage model is formulated to describe the material degradations. Finally, this model is rewritten in order to reproduce the damage influence on the hydromechanical behaviour of the material. With some micromechanical analysis results the expression of the Biot coefficient tensor in function of the damage variable is obtained.
