THE NATURE OF STRESS AND VELOCITY CHARACTERISTICS FOR CRITICAL STRESS STATES

The nature of whether stress and velocity characteristics do or should coincide in the plane strain deformations of soils and granular materials in the development of the constitutive equations of such materials is discussed in this technical note. The technical note concludes that the presence of 2 families of stress characteristics in a critical state of stress removes the objection that such hardening models have non-coincident stress and velocity characteristics. In a fully developed flow, when viewed as the critical state limit of a volumetric hardening model, the velocity characteristics are orthogonal and do not coincide with the Sokolovskii stress characteristics of classical Mohr-Coulomb theory. Instead the velocity characteristics coincide with the limiting stress characteristics associated with the preceding hardening deformation.
