Thermodynamic and physical principles are applied in conjunction with the concepts of endochronic plasticity to develop a theory of constitutive behaviour of soils with dilatant capability. Three separate constitutive models are derived within the framework of the proposed theory, all capable of accounting for shear–volume coupling of soil within the context of endochronic plasticity. One specific model is singled out as the most appropriate on the basis of its analytical simplicity and the plausibility of its thermodynamic and physical foundations. A simple example is worked out for the purposes of illustration.
