The Effect of Failure Criteria on Liquefaction and Pore Pressure Prediction in Non-Plastic Soils

open access: yesGeotechnics
Since the 1960s, cyclic triaxial tests have been utilized to assess the liquefaction susceptibility of cohesionless soils. While standardized procedures exist for conducting cyclic triaxial tests, there remains no universally accepted criterion for ...

Static liquefaction as a form of material instability in element test simulations of granular soil [PDF]

open access: yesArchives of Civil Engineering
Static liquefaction is a form of unstable behaviour of granular soil. It is most common in saturated loose sands under monotonically loaded undrained conditions.

Yielding and Flow Liquefaction of Loose Sand

open access: yesSoils and Foundations, 2002
Abstract: The relationship between the shapes of the yield surface and the undrained effective stress path (UESP) of loose sand is investigated for triaxial loading conditions. It is shown that the UESP can be used in the construction of capped yield surfaces for sands.
