A Modified Bounding Surface Hypoplasticity Model for Sands
A modified bounding surface hypoplasticity model is developed to capture distinct dilatancy behaviors of sandy soils during various phases of cyclic loading. The model features a new modulus formulation, a phase transformation surface that is dependent on a state variable and soil density. The effects of accumulated plastic strains on the plastic moduli are also considered. The modified model improves simulation of cyclic mobility and post-liquefaction behavior of both loose and dense sands. The model capacity is demonstrated by comparing the model simulations with a series of undrained cyclic simple shear tests on Fraser River sand.
