Phase-field modeling has already proved to be a suitable framework to predict the initiation and propagation of drying cracks in variably saturated porous media. In this paper, we focus on some fundamental modeling aspects which have not yet been giv

Solving dynamic problems for fluid saturated porous media at large deformation regime is an interesting but complex issue. An implicit time integration scheme is herein developed within the framework of the u–w (solid displacement–relative fluid

Phase-field modeling of fracture in variably saturated porous media

Autor: T. Cajuhi, Lorenzo Sanavia, L. De Lorenzis

We propose a mechanical and computational model to describe the coupled problem of poromechanics and cracking in variably saturated porous media. A classical poromechanical formulation is adopted and coupled with a phase-field formulation for the fra

International audience; This paper deals with the hydromechanical modelling of the initiation of failure in soils with particular reference to landslides. To this end, localized and diffused failure modes are simulated with a finite element model for
