000004651 520__ $$2eng$$aViscous aspects of the stress-strain behaviour of sand under general stress conditions were evaluated by performing special drained triaxial compression tests on relatively dense Toyoura sand. The yield characteristics of sand were identified by applying unload/reload cycles under otherwise monotonic loading at a constant strain rate. It is shown that the yield stress observed is significantly affected by viscous effects associated with changes in the strain rate or creep deformation or both not only along a fixed stress path with a single stress variable, but also in a two-dimensional stress space of triaxial compression. It is argued that it is necessary to take into account viscous effects in the constitutive modeling for sand.
