This paper describes a new formulation of the material point method (MPM) for solving coupled hydromechanical problems of fluid-saturated soil subjected to large deformation. A soil-pore fluid coupled MPM algorithm based on Biot's mixture theory is propose ...
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) network. The objective is to benchmark different approaches to constituti ...
This paper aims to identify and evaluate various critical mechanisms associated with the processes of desiccation shrinkage in drying silty soils. A previously developed 1D bundle-of-tubes model is refined to simulate the various stages of drying shrinkage ...
Cracking is a most unwanted development in soil structures undergoing periodic drying. Desiccation cracking arises in the apparent absence of external forces. Hence, either an internal, self equilibrated stress pattern resulting from kinematic incompatibil ...
This paper aims to identify and quantitatively evaluate various critical mechanisms associated with the processes of desiccation shrinkage and cracking in drying silty soils. A previously developed 1D bundle-of-tubes model is refined to simulate the variou ...
Experimental findings on the hysteresis of the soil water retention curve, relating the degree of saturation to the matric suction, have to be superimposed with the aspects due to the soil matrix deformation. In order to set a comprehensive model for the r ...
Heavy rainfall can lead to shallow slips in slopes that are initially in a state of partial water saturation. Multiphysics numerical modelling approaches taking into account the involved physical key processes in variably saturated soils during rainfall ev ...

We propose a scaling law that explicitly correlates the macroscopic yield stress of weakly attractive nanoparticle networks with features of the microscopic aggregates that form the percolating gel. The proposed law correctly predicts experimental data obt ...
This paper presents an innovative double cell triaxial system developed for better understanding of the complex thermo-hydro-mechanical behaviour of soils. In addition to the conventional triaxial mechanical testing, the equipment is aimed to perform sucti ...
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 ...
