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 …

Models for thermo-hydro-mechanical behavior of saturated/unsaturated porous media are
reviewed. The necessary balance equations are derived using averaging theories …

The coupling between subsurface flow and geomechanical deformation is critical in the
assessment of the environmental impacts of groundwater use, underground liquid waste …

Current alternative choices of stress state variables in unsaturated soils are described and
compared, with a special focus on the use of an effective stress. Experimental data on …

The range of problems that geotechnical engineers must face is increasing in complexity
and scope. Often, complexity arises from the interaction between the soil and the …

The effective stress principle, conventionally applied in saturated soils, is reviewed for
constitutive modelling purposes. The assumptions for the applicability of Terzaghi's single …

Part 1 of the paper presents a new numerical model of hygro‐thermal and hydration
phenomena in concrete at early ages and beyond. This is a solidification‐type model where …

A mathematical model for analysis of hygro-thermal behaviour of concrete as a multi-phase
porous material at high temperatures, accounting for material deterioration, is presented …

Unconventional geomaterials often exhibit multi-modal pore size distribution. We have
developed a comprehensive framework for porous media exhibiting multiple porosity scales …

Physical phenomena in heated concrete, leading to thermal spalling are discussed.
Contribution of the stored elastic energy and vapour pressure build-up to the kinetic energy …
