An unsaturated soil is a three-phase material that is ubiquitous on the earth's surface. The
fully saturated and completely dry states are just two limiting conditions of an unsaturated …

Based on the equations for volume change and saturation variation proposed in the
companion paper [37], an alternative constitutive framework is presented for interpreting …

The two stress-state variable approach has been widely used in interpreting unsaturated soil
behaviour. However this approach cannot take into account the effect of degree of saturation …

An unsaturated soil is a state of the soil. All soils can be partially saturated with water.
Therefore, constitutive models for soils should ideally represent the soil behaviour over …

The paper presents a collaborative piece of research undertaken by seven research teams
from different universities within the 'Mechanics of Unsaturated Soils for Engineering'(MUSE) …

Unsaturated soil behaviour, such as volume change, shear strength and yield stress, is
usually interpreted and modelled in terms of stress and suction. This approach is consistent …

A state-dependent elasto-plastic constitutive model for both saturated and unsaturated soils
is presented in this paper. The model, which is developed under an extended critical-state …

This study presents a sophisticated elastoplastic constitutive model for unsaturated soil
using Bishop-type skeleton stress and degree of saturation as state variables in the …

The degree of saturation (S) of soil can be separated into two components: the degree of
capillary saturation (S′) that is based on the capillary water and the degree of adsorptive …

The coupled mechanical and water retention elasto-plastic constitutive model of Wheeler,
Sharma and Buisson (the Glasgow coupled model, GCM) predicts unique unsaturated …
