Programma sintetico The course covers fundamental evidence and modelling approaches for soils in unsaturated states. The lectures start from fundamental physical processes, including the choice for alternative variables to describe them. Experimental testing equipment and procedures are introduced, including microstructure investigation and non-destructive indirect testing. Paradigmatic experimental results are presented and discussed. Coupling between the hydraulic and the mechanical response is highlighted, together with the role played by the evolving microstructure. Modelling principles are introduced, discussing the choice for kinematic and static variables and alternative strategies to extend existing models to unsaturated states. The state surface approach will be introduced for both the hydraulic and the mechanical response, before diving into the framework of elastoplasticity with generalised hardening, which may include information on the microstructure. Uncoupled and coupled hydro-mechanical models are discussed. To address engineering problems, the fully coupled three-phase balance equations are formulated. Implications and shortcomings of simplified two-phase approaches are analysed with reference to paradigmatic applications. Setting initial conditions and boundary conditions is discussed, before going towards numerical implementation and analysis via Finite Element approximation.
