Seminar: Strain Localization in Partially Saturated Porous Media: Thermodynamics, Numerical Formulation, Applications

It is presented an analysis of discontinuous displacements and corresponding singular strains in variably saturated porous media, considering also the discontinuous fl ows and the corresponding singular distributions of fl uid contents, to model the accumulation/drainage of gas and liquid along the localized failures . In this analysis, the continuum response is described by a three-phase poroplastic model, whose hyperelastic part is a simplifi ed version of more general laws recently developed within a computationally oriented thermodynamic approach based on Biot work .
