Research interest in the thermo-mechanical behaviour of unsaturated soils is growing as a result of an increasing number of geomechanical problems involving both thermal and unsaturated effects. In this framework, this paper addresses a unified thermo-mech ...
This paper addresses a new, unified thermo-mechanical constitutive model for unsaturated soils through a coupled study. In the context of elastoplasticity and the critical state theory, the model uses the concepts of multimechanism and bounding surface the ...
Soil is a particulate material that may undergo irreversible strain as the relative positions of the constituent particles change. That irreversible behaviour may be induced not only by an external stress variation but also by temperature or suction change ...
Current models of the elasto-plastic behaviour of unsaturated soils contain important underlying assumptions that have not been tested due to a lack of adequate experimental data. To address this issue, the objective of this paper is to provide a comprehen ...
An introduction to the constitutive modelling of unsaturated soils is presented. To facilitate understanding by the inexperienced reader, the paper considers the basic aspects of modelling of the behaviour of unsaturated soils from a qualitative point of v ...
This paper presents a unified thermo-mechanical experimental study on a remoulded unsaturated sandy silt and brings a contribution to the understanding of the fundamental mechanics of unsaturated soils in non- isothermal conditions. The experimental progra ...
Prediction of water flow and transport processes in soils susceptible to structural alteration such as compaction of tilled agricultural lands or newly constructed landfills rely on accurate description of changes in soil unsaturated hydraulic conductivity ...
The state-of-the-art report presented herein is aimed at documenting, to the largest extent possible, some of the recent advances in laboratory testing of unsaturated soils for stress-strain-strength-stiffness characterization under suction-controlled isot ...
This paper introduces an unconventional constitutive model for soils which deals with a unified thermo-mechanical modelling for unsaturated soils. The relevant temperature and suction effects are studied in light of elasto-plasticity. A generalized effecti ...
Mechanics of porous media is the study of porous materials whose mechanical behaviour is significantly influenced by the pore fluid. This handout is devoted to the theory of deformation, strength, flow and multiphase coupling in porous media. The mechanics ...
