DOI: 10.1016/j.compgeo.2017.11.010
Abstract: Abstract The present study has developed a constitutive model for both saturated and unsaturated soils. The model considers the effect of mechanical and hydraulic loading on the soil behavior in critical state framework. The mechanical… read more here.

DOI: 10.1103/physrevlett.130.166102
Abstract: Using discrete element method simulations, we show that the settling of frictional cohesive grains under ramped-pressure compression exhibits strong history dependence and slow dynamics that are not present for grains that lack either cohesion or… read more here.
