Interpretation of stresses and strains in unsaturated fine-grained soils (2014)
Presentation / Conference Contribution

The derivation of Eq. (1) relies on the soil particles and water phase combining and forming aggregates under equilibrium conditions. This may be shown to minimise the thermodynamic potential and is a requirement of equilibrium conditions. The equati...

Electrical resistivity is a physical property that defines how a material resists the flow of electricity. The resistivity method is therefore based on the principle that the potential drop across a pair of electrode (P1 and P2) associated with DC or...
