Abstract
External measurements of specimen distortion define the macro-mechanical straining that must satisfy the overall continuity and work criteria. Internal to a soil specimen, the stresses and strains must also satisfy compatibility and energy dissipation. The strains at the internal micro-mechanical level are of greater magnitude than those at the macro-mechanical level because of the need to account for a number of identifiable energy dissipation components, though the net effects must balance the macro-mechanical measurements. This includes the micro-mechanical level of structure defined by the aggregates (combined volume of water and soil particles) and air voids. An analysis of triaxial experimental data of the stresses and strains at the aggregate level of micro-mechanical straining is presented.
