This work describes the development of a numerical module with a multiphysics structure to simulate the thermo-hydro-chemo-mechanical behavior of compacted bentonites. First, the conceptual model, based on the state-of-the-art formulation for clay-ba

This paper describes a model for the prediction of sinkhole collapse for two-dimensional and axisymmetric conditions. The model explains the arching effect on the threshold of collapse by a catenary arch or dome that tries to redirect the self-weight

A macroscopic model based on a double-porosity approach is proposed to simulate the swelling caused by the subdivision of particles and aggregates that occurs when bentonites are hydrated under a high water content and low confinement. In the model,

This article proposes an approach to ensure consistency between constitutive formulations used in double-porosity models when the macrostructural void ratio, eM, is very small. These formulations model processes of different physical natures and ther

The temperature effect on the microstructure deformability of compacted bentonites was assessed using a Clausius-Clapeyron type equation. To this end, vapor adsorption data obtained at different temperatures under low water content conditions was use
