A constitutive model is presented to describe the stress-strain behaviour of sand while unsaturated. The model is formulated using bounding surface theory and is presented in a critical state framework using the concept of effective stress. The model is validated against triaxial shear and oedometric compression tests. A single set of material parameters are required for the complete constitutive modelling.
