Abstract: A new type of constitutive theory for granular soil, hypoplastic constitutive theory which was originated in recent 30 years, is introduced in detail. Comparing with the elastoplatic theory, the hypoplastic constitutive expression has automatically implied some basic concepts and factitious assumptions, e.g. decomposition of elastic strain and plastic strain, yield function, hardening law, plastic potential, flow rule and so on. The critical state of Gudehus-Bauer hypoplastic model is analyzed. Besides, the numerical simulation of triaxial test and cyclic shear test were illustrated and the results show that the model can grasp the main mechanical properties of granular soil, e.g. anelasticity, nonlinearity, dilatancy and so on.

Key words: granular soil, constitutive theory, hypoplasticity, critical state, Gudehus-Bauer model, numerical simulation
