ABSTRACT
Undrained cyclic torsional and triaxial shear tests were perfomed on hollow cylindrical specimens of dense Toyoura sand, which were consolidated isotropically after preparation by airpluviation. At several stress states, quasi-elastic deformation properties were measured by applying very small amplitude cyclic torsional and vertical loads. Some of the results could be explained by considering inhewrent and stress state-induced anisotropy in modeling of elastic deformation characteristics and by correcting for the effects of membrane penetration. Degradation in the values of elastic shear modulus and Young's modulus was observed during liquefaction when compared to those measured during isotropic consolidation.(AU)
