ELASTO-PLASTIC STRESS-STRAIN THEORY FOR COHESIONLESS SOIL WITH CURVED YIELD SURFACES

An elasto-plastic stress-strain theory for cohesionless soil with curved yield surfaces is developed on the basis of soil behaviour observed in laboratory tests. This theory is applicable to general three-dimensional stress conditions, but the parameters required to characterize the soil behaviour can be derived entirely from results of isotropic compression and conventional drained triaxial compression tests. The theory is shown to predict soil behaviour under various loading conditions with good accuracy. Of special interest is its capability of predicting soil behaviour under drained as well as undrained conditions over a range of confining pressures where the behaviour changes from that typical of dense sand to that typical of loose sand. Work-hardening as well as work-softening is incorporated in the theory. /Author/TRRL/
