Modelling strain softening of structured soils

Abstract

Strain softening response of structured soil is more complicated than that of reconstituted soil. After comparatively introducing the unified hardening model for over-consolidated soil (UH model), and the unified hardening model for structured soil (structured UH model), the simulations of strain softening by the 2 models are analyzed from the visual angle of mathematic description. Comparisons between model simulations and test data of strain softening for different soils are illustrated at last, and the reasonability of model descriptions for different strain softening are verified.
