Abstract: Rotational hardening is the constitutive ingredient of clay plasticity models that allows rotation of the yield surface in stress space to simulate, more realistically than isotropic models, the stress-strain response under ...

Abstract: Unsaturated shear strength (τus) is a critical parameter in many geotechnical engineering designs, including embankment stability assessments and slope antiskid design. This paper investigates the hydromechanical behavior ...
