Finite Element Analysis of Hydro-Mechanical Coupling Effects on Shear Failures of Fully Saturated Collapsible Geomaterials

The fully coupled diffusion-deformation processes occurring within porous geomaterials - such as sand, clay and rock - are of interest to numerous geotechnical engineering applications. In this work, a stabilized enhanced strain finite element procedure for poromechanics is integrated with an elasto-plastic cap model to simulate the associative and non-associative hydro-mechanical responses of fluid-infiltrating, biphasic, collapsible, porous...
