Abstract: Volume expansion can occur in overconsolidated clay during shear loading and heating. However, the volume expansion mechanisms driving these two phenomena are different from each other, and it is important to propose a ...

Abstract: Based on the existing unified hardening model, the double-state parameters unified hardening (DPUH) model is proposed, which can take into account the initial density and confining pressure dependent characteristics and ...

Abstract: Overconsolidated (OC) clay has a strong dilatancy property, which has a significant effect on ultimate strength and deformation. Compared with normal consolidated (NC) clay, OC clay tends to show a higher strength–stress ...

Abstract: The geotechnical materials formed by natural deposition usually have transverse isotropic properties, and the transverse isotropic properties not only have a direct influence on the deformation of geotechnical materials ...

Abstract: Most clays, either naturally deposited or man-made, possess a certain degree of overconsolidation owing to tamping, cyclic loading, erosion, excavation, and/or changes in groundwater tables. An easy-to-use constitutive ...
