“…local level). This is the common procedure used in the literature for finite element analysis involving unsaturated soils [5,38,43], because these two increments (i.e. , s) can be easily approximated at the corresponding integration points, once the nodal displacements and pore fluid pressures increments have been found from the discretized global equations.…”

You are advised to consult the publisher's version if you wish to cite from it.http://eprints.gla.ac.uk/150055/ Comparison of model simulations with experimental results for the full set of Sivakumar's isotropic loading stages demonstrates that the model is able to predict accurately the variation of both specific volume and degree of saturation during isotropic stress paths under saturated and unsaturated conditions.

“…The authors have not been able to identify any existing analytical solutions for inception of strain localization in unsaturated soils. Borja (2004) developed a mathematical framework for numerical analysis of three-phase deformation and strain localization of partially saturated porous media. The framework was used to detect the onset of strain localization for plane strain compression at the constitutive level.…”

“…The framework was used to detect the onset of strain localization for plane strain compression at the constitutive level. Borja (2004) used the degree of saturation as the effective stress parameter. Schiava and Etse (2006) conducted a numerical assessment of strain localization in unsaturated soils at constant suction.…”

“…Also all the following equations are written in isothermal conditions, which evidently leads to not considering the temperature gradient and limits the modelling of the evaporation (Gawin, Sanavia, & Schrefle, 1998). If the water is assumed incompressible, the balance of water mass is (Borja, 2004):…”

In some arid and semi-arid regions, different types of infrastructure assets suffer from degradation of the roads, the embankment failures, erosion due to cyclic hydraulic actions and the effects of rainfall infiltration on slopes. Typical cases, such as the national roads in the north-west of Tunisia (Béja city) have been affected dramatically. Recent landslide is manifested in this region, especially in a plastic clay soil. Stability problems are caused by soil saturation and the presence of abundant cracks which are developed after a long dry summer. In fact, due to geotechnical problems, the annual loss due to the damage is estimated at $1 million in Béja area (30 km 2 ). The effect of rainfall infiltration into the unsaturated clay during wet seasons characterised by either long duration low intensity rain or short duration high intensity rain have been analysed. The elastoplastic Barcelona Basic Model (BBM) has been used and soil movements leading to slope failure were calculated according to the unsaturated state evolution. The effects of cyclic hydraulic paths on the yield function have also been investigated. The yield function evolution depends on the cohesion and the apparent consolidation stress variations. The numerical calculations were evaluated against the field measurement displacements.
