Abstract

Discrete particle simulations of granular materials under 2D, isochoric, cyclic pure shear have been performed and are compared to a recently developed constitutive model involving a deviatoric yield stress, dilatant stresses and structural anisotropy. The original model shows the cyclic response qualitatively, but suffers from an artificial drift in pressure. With a small modification in the definition of the stress anisotropy and an additional limit-pressure term in the evolution equation for the pressure, it is able to show the transient as well as the limit cycles. The overall goal – beyond the scope of the present study – is to develop a local constitutive model that is able to predict real life, large scale granular systems.
