The effect of principal stress rotation and intermediate principal stress changes on the liquefaction resistance and undrained cyclic response of Ottawa sand [PDF]

Journal of Geotechnical and Geoenvironmental Engineering, 2021
In laboratory testing, the liquefaction resistance of sands is typically evaluated using cyclic triaxial and simple shear tests. These tests cannot be used in a rigorous manner to systematically assess the effects of principal stress rotation and ...

Effect of intermediate principal stress on the mechanical behavior of angular sand

Soil Behavior and Geomechanics, 2014
Sand is a naturally occurring, cohesionless, granular material with varying morphology. It has been well studied as a model frictional material, and the strength of the sand ensemble is derived from the inter-granular friction.
