heal.abstract	This paper evaluates the predictive capabilities of an effective soil model through comparison with experimental results of tests on a fine-medium sand. Comparison is made at various densities, mean effective consolidation stresses and drainage conditions. The current investigation focuses on the prediction of the stress paths and stress-strain behaviour using experimental results from specimens subjected to torsional loading in the hollow cylinder apparatus. The results of the numerical analysis have shown good correlation between the response predicted from the constitutive model and obtained from torsional shear under drained loading conditions. However, for torsional loading under undrained conditions correlation is poor especially regarding the stress-strain response of the specimens for large shear strains. © 2005 Civil-Comp Press.	en
