Meso-Scale Modeling of Deformation Banding in Saturated Dense and Loose Sands

This paper presents results obtained from finite element simulations of dense and loose samples of sand loaded under globally undrained plane strain conditions. The effective behavior of the sands is captured using a newly developed elastoplastic model for granular materials based on critical state theory (CST). The novelty here is the ability of the constitutive model to account for inhomogeneities in the density field at the meso-scale while...
