An elasto-plastic model for unsaturated soil incorporating the effects of suction and degree of saturation on mechanical behaviour
TL;DR: In this article, an elasto-plastic model for unsaturated soils is presented that takes explicitly into account the mechanisms with which suction affects mechanical behaviour as well as their dependence on degree of saturation.
Modelling the mechanical behaviour of expansive clays
TL;DR: In this article, a simple formalism is presented to model the behavior of expansive clays, where two levels of structure are considered, one for wetting and the other for drying, and a mathematical formulation of the model is described and its performance finally assessed by comparison with laboratory tests.

A microstructurally based effective stress for unsaturated soils
TL;DR: In this paper, the authors compared several alternative stress state variables in unsaturated soils, with a special focus on the use of an effective stress, and suggested that the proportion of suction contributing to the effective stress is often much smaller than predicted by the term "suction times degree of saturation" generally used in effective stress expressions of the Bishop type.

In situ behaviour of a stiff layered clay subject to thermal loading : observations and interpretation
TL;DR: In this article, an interpretation of an in situ heating test carried out on Opalinus clay in the Mont Terri underground laboratory is presented, which provides an opportunity to examine the integrated thermo-hydro-mechanical response of this sedimentary clay.
Fast physically-based model for rainfall-induced landslide susceptibility assessment at regional scale
TL;DR: In this paper, a physically-based model called "Fast Shallow Landslide Assessment Model" (FSLAM) was developed to calculate large areas (>100 km2) with a high-resolution topography in a very short computational time.
