The critical state and steady state of sand: A literature review
The critical state and steady state theories are widely accepted for simulating the soil behavior and providing a basis for liquefaction evaluation and constitutive modeling. However, there was conflicting evidence regarding the critical state and steady state of sands in the last decades. In some cases, the critical state and steady state are taken to be identical and in others they differ significantly. Whether they are the same or not remain a hot academic debate to date. This paper provides a critical review on the origin and history of the critical state and steady state of sands, which identifies conflicting evidences and discusses the influencing factors on the existence and uniqueness of critical state and steady state. Based on a critical review of literature, it is concluded that the steady state concept is a refinement of the critical state concept and the uniqueness of the critical state and steady state was affirmed. Special care should be paid in the laboratory techniques in order to accurately measure the critical state and steady state due to the numerous influencing factors of them.
