Critical state plasticity. Part VII: Triggering a shear band in variably saturated porous media
Bifurcation Critical state theory Heterogeneity Mixed formulation Shear band Unsaturated porous media

In a previous paper (Part VI), the impact of spatially varying density on the localization of deformation of granular materials has been quantified using mesoscopic representations of stresses and def...
On the effective stress in unsaturated porous continua with double porosity
Constitutive behavior Geological material Granular material Microstructures Porous material
2015/7/1
Using mixture theory we formulate the balance laws for unsaturated porous media composed of a double-porosity solid matrix infiltrated by liquid and gas. In this context, the term ‘double porosity’ pe...
We present a finite element model for the analysis of a mechanical phenomenon involving dynamic expulsion of fluids from a fully saturated porous solid matrix in the regime of large deformation. Momen...
Cam-Clay plasticity. Part V: A mathematical framework for three-phase deformation and strain localization analyses of partially saturated porous media
Cam-Clay plasticity
2015/7/1
We present a mathematical framework for deformation and strain localization analyses of partially saturated granular media using three-phase continuum mixture theory. First, we develop conservation la...
On the mechanical energy and effective stress in saturated and unsaturated porous continua
mechanical energy effective stress saturated and unsaturated porous continua

This paper has two objectives: (a) to formulate a mechanical theory of porous continua within the framework of strong discontinuity concept commonly employed for the analysis of strain localization in...
Effects of bottom shear stresses on the wave-induced dynamic response in a porous seabed: PORO–WSSI (shear) model
Bottom shear stresses Wave-induced dynamic response Porous seabed “u–p&rdquo approximation Biot’s theory
2012/2/28
When ocean waves propagate over the sea floor, dynamic wave pressures and bottom shear stresses exert on the surface of seabed. The bottom shear stresses provide a horizontal loading in the wave-seabe...
