ELASTO-PLASTIC BEHAVIOR OF K0-CONSOLIDATED CLAY IN TORSION SHEAR TESTS

A series of torsion shear tests was performed along various stress-paths on hollow cylinder specimens of k0-consolidated clay to investigate the influence of rotation of principal stresses on the stress-strain and strength characteristics. The effects of stress-paths and reorientation of principal stresses were mainly observed in the prefailure stress-strain behavior. The experimentally obtained failure surface from torsion shear tests could practically be modeled by an isotropic failure criterion. Coupling effects between stresses and strains were observed when torsion shear and vertical normal stresses were applied. The work-space for torsion shear tests was illustrated, and the relation between stresses and strain increments was also studied in the work-space.(a)
