The Yielding of Unsaturated Granular Materialsribution inspired by the capillary theory. It is shown that this approach motivates a macroscopic Helmholtz free energy that, together with the breakage dissipation, captures the coupling between mechanics and hydraulics and provides a novel theoretical interpretation for the classical notion of loading-collapse curve.

偉大

Fractal Soil-Water Characteristics with Hysteresisof a body is controlled by the largest throat connected to it. As suction is reduced along the main wetting curve, the absorbed water collects in the smallest bodies and throats first, then fills larger bodies and throats in order of size.

The Effective Stress in Unsaturated Soils: Insights from Thermodynamicso the effective stress formulation. The results of the proposed thermodynamic approach support the previous studies based on micromechanics by emphasizing on the tensorial nature of the different terms involved in the effective stress formulation as well as the importance of the interfacial energy in mechanical behavior of unsaturated soils.

The Meaning of Stresses and Strains in Unsaturated Soils aggregates (combined volume of water and soil particles) and air voids. An analysis of triaxial experimental data of the stresses and strains at the aggregate level of micro-mechanical straining is presented.

Modelling Volume Change Behaviour for Unsaturated Soils in the Stress–Saturation Spaceree of saturation and is interpolated from the known compressibility at the fully saturated state and that at a dry state. The proposed model for volume change is validated against a variety of experimental data in literature.
