A fundamental experimental study of sand behavior under low stress ratio proportional loading wherein all strain components are contractant is presented. Experimentally observed behavior under stress conditions of the triaxial test led to a coherent framework for representing proportional loading stress-strain response. The stress-strain relationship formulated incorporates relative density as an inherent independent state variable and does not require appeal to material isotropy.
