Abstract

The paper examines the nature of plastic flow in granular materials under loading that involves rotation of principal stress axes. Examples in engineering practice involve offshore foundations under wave loading, earthquake loading, pavement and railway track foundations, among others. Micro-scale investigations through discrete element modelling (DEM) with a focus to non-coaxiality of incremental plastic strains to stress tensors are presented. Results can enter constitutive models for numerical applications through an amended plasticity flow rule.
