• A constitutive relationship, known as CARMEL, is proposed to predict the behaviour of anisotropically consolidated clay. Based on the principles of critical state soil mechanics the model has a non-associated flow rule and accommodates both isotropic and rotational strain hardening. A characteristic of the CARMEL model is that it can represent the changes in stress-strain behaviour of soil caused by variations in stress induced anisotropy. This permits the modelling of long stress paths, during which the induced anisotropy of the soil can be greatly changed. To assess the model, data from stress path triaxial tests reported in the literature have been predicted. Comparisons between the experimental data and predictions of CARMEL show good correlations which significantly improve on predictions using Modified Cam Clay, an isotropic associated model.
