Constitutive analysis of the mechanical anisotropy of Opalinus Clay

Lyesse Laloui, Bertrand François, Mathieu Nuth, Simon Salager

This paper aims to analyse the anisotropic features of behaviour of Opalinus Clay using the theory of plastic multi-mechanisms. The results of triaxial tests conducted with different load levels and directions showed that the mechanical behaviour of this s ...

An investigation into the water retention behaviour of deformable soils

Lyesse Laloui, Mathieu Nuth, Alessio Ferrari, Simon Salager

The paper presents an experimental and modelling approach for the soil water retention behaviour of two deformable soils. The objective is to investigate the physical mechanisms that govern the soil water retention properties and to propose a constitutive ...

Desiccation shrinkage of non-clayey soils: multi-physics mechanisms and a microstructural model

Lyesse Laloui, Hervé Péron

Analysis of macroscopic desiccation shrinkage experiments indicates that most, but not all of the shrinkage during drying occurs while soil is still saturated. Shrinkage practically ceases and air starts to penetrate the soil, when the water content is sti ...

Advances in the analysis of thermo-active foundations

Lyesse Laloui, Thomas Mimouni, Fabrice Dupray

Energy geostructures are foundations equipped with absorber pipes, exchanging heat with the surrounding ground. They provide a good heat source for the heating and cooling of buildings but the temperature variations they undergo bring new challenges. Therm ...
