Abstract

This study is intended to describe the influence of the initial static shear stress on post-cyclic deformation characteristics in triaxial compression and extension tests on Toyoura sand that underwent pre-consolidation under isotropic and anisotropic consolidation stress states in the compression and extension domains. This study specifically addressed the effects of principal stress direction and principal stress reversal, which were developed during post-cyclic monotonic undrained shear when the cyclic load was given to the specimen. Results revealed that both the stress reversal and stress direction during compression and extension shear produced a marked degradation in deformation modulus as well as undrained strength.
