title = "A Micromechanical Model for Unsaturated Soils Based on Thermodynamics",
abstract = "This paper presents a micromechanical model for unsaturated granular soils based on thermodynamics. The dissipation of energy is examined at the level of the particle contacts. The total Helmholtz free energy is separated between a mechanical and a hydraulic part, each of which is a function of either the elastic displacement or the degree of saturation at the micro scale. The dissipation of energy, assumed to be frictional in origin, is a function of the plastic displacements at the micro scale. Both the Helmholtz free energy and the dissipative energy are volumetrically averaged from the micro to the macro scale. The Chang-Hicher micromechanical model has been adopted for the deformation of the skeleton, whereas a hydraulic potential dependent on the size of the particles has been chosen for the expression of the water retention.",
