DOI: 10.1007/s11440-021-01231-8
Abstract: When soil particles break, the particle size distribution (PSD) becomes a variable in the same way as other variables like void ratio, soil structure and anisotropy, etc. To consider particle breakage in a constitutive model,… read more here.

DOI: 10.1016/j.compgeo.2017.03.008
Abstract: Abstract A simple semi-hyperbolic state-dependent constitutive model for sand-structure interfaces is proposed. The model formulation is consistent with critical state soil mechanics since void ratio evolves continuously with shear strain from initial state towards asymptotic… read more here.
