Abstract:

Inferences regarding the character of the pointwise or material flow behavior for cohesionless soils are drawn from the results of a series of tests on a sand system. Specifically these inferences are that normality to the failure surface may be preserved for projections of the plastic strain increment vector onto planes of constant hydrostatic pressure pi-planes and that the angular deviation from normality to the failure surface for projections of the plastic strain increment vector onto planes perpendicular to the pi-plane may, as a first approximation, be considered constant. Statistical methods were employed to establish a nest of failure envelopes in the force space of the applied tractions with a parametric dependence on the relative density at failure. The results of this analysis led to the inferences regarding material behavior.
