Abstract

Simulations of the undrained triaxial behaviour of sand using 3DDEMare described.Three types of undrained behaviour: flow, limited flow and non-flow were observed in DEM simulations, as is commonly observed in most laboratory studies. Three consolidation paths: isotropic, anisotropic K =σ' 3/σ'1 =0.50 and K0 were assigned to observed their effect on undrained behaviour.The stress ratio,K =σ' 3/σ'1 duringK0 consolidation varied significantly with applied σ1 which is not in line with the widely used Jaky equation.However, consolidation paths did not show a significant effect on undrained stress-strain and steady state behaviour. A unique steady state line was achieved irrespective of the consolidation history prior to undrained shearing. © 2015 Taylor & Francis Group, London.
