Review of fundamental principles in modelling unsaturated soil behaviour
D Sheng - Computers and Geotechnics, 2011 - Elsevier
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 …

A new modelling approach for unsaturated soils using independent stress variables
Although a number of constitutive models for unsaturated soils exist in the literature, some
fundamental questions have not been fully answered. There are questions related to (i) the …

Interpretation of unsaturated soil behaviour in the stress–saturation space, I: volume change and water retention behaviour
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 …
