A thermomechanical model for saturated soil at small and large strains

Many elastoplastic models have been developed for simulating thermomechanical behaviour of saturated soil. Although the yield surface of these models shrinks with temperature, its shape is always assumed to be independent of temperature. This simplification may induce errors in predicting thermal effects on shear behaviour. Furthermore, existing models tend to focus on thermomechanical behaviour at large strains. Behaviour such as the degradation of the shear modulus with strain at small strains (
