Abstract
A state dependent constitutive model, from the family of SANISAND models, was adopted to develop a constitutive model for Sydney sand to predict static liquefaction behaviour and to simulate cyclic instability behaviour. The detail formulation of the constitutive model within the critical state soil mechanics (CSSM) framework was presented first. The model was then used to predict a static liquefaction behaviour which showed good match for characteristic behaviour of undrained tests. The model was also used to evaluate the link between static and cyclic instability behaviour. Although there were some limitations in the model simulation, they shows a good agreement with the literature that static liquefaction and cyclic instability are linked through the instability zone.
