Modeling the relation between suction, effective stress and shear strength in partially saturated granular media
… matrix. The remaining stress is carried by the pore fluid in the form of pore pressure. In unsaturated soils, the coexistence of water and air results in negative pore pressure, which are termed "soil suction". A clear link between soil suction and effective stress has not yet been established. …

The mechanisms involved during the desaturation process of a porous matrix
… behavior has been argued to be a function of negative pore pressure or matric suction. All the unsaturated soil behavioral issues contain a single underlying question; what is the nature of soil suction? Nature refers to the physical phenomenon that generates soil suction and changes with …

Two-scale modeling of transport mechanisms and quality changes during frying of foods
… rate of evaporation, temperature distribution, pore and gas pressures. Average absolute deviation (AAD) for the predicted and the experimental data was calculated for the model validation. Simulations were also used to predict the quality (texture and color) of products during frying. Rice …

Constitutive Modelling of Shear Localisation in Saturated Dilative Sand
Undrained deformation of dilative sand generates negative excess pore pressure. It enhances the strength which is called dilative hardening. This increased suction is not permanent. The heterogeneity at the grain scale triggers localisations causing local volume changes and associated drainage. The …
