dc.description.abstract	Results from an experimental program on Ottawa sand subjected on generalized monotonic loading are presented. The experimental program was conducted on both solid and hollow cylinder specimens, including isotropic, triaxial compression and torsional loading at various stress levels. The results are used in an attempt to numerically simulate the behaviour of the sand using Lade’s Double Hardening model and evaluate is predictive capabilities. The calibration procedure is thoroughly presented. The numerical analysis has been based on the Finite Element Method (FEM) and by using the finite element software ICFEP (Imperial College Finite Element Programme). Comparison between experimental data and model predictions shows good agreement for all practical purposes highlighting the potential of complex elasto-plastic models in predicting soil behaviour.	el
