Constitutive modeling of geomaterials : advances and New applications. "On the modeling of transition from a Diffuse to a localized Damage"
Résumé
An approach to model long term hydromechanical behaviour of rock masses around underground excavations is proposed. implemented in a classical finite element numerical code this approach combine in one hand a continuum model todescribe the progressive damage and strain localization and a fracture mechanics XFEM based numerical procedure to model the behaviour of fractured mass once the macrofracturing takes places
