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, 2022 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 intermediate principal stress changes on the undrained cyclic response of sands.
