Meso-Scale Evolution of Shear Localization Observed in Plane Strain Experiment on Kaolin Clay
Undrained plane strain compression experiments were conducted on slurry consolidated kaolin clay samples to elucidate the mechanism of shear localization in clays. The biaxial device was heavily internally instrumented, thus enabling the multiple boundary displacement measurements. These measurements were combined with boundary digital imaging to compute and verify displacements of the shear band. The orientation of shear band was determined from photographs thus enabling the computation of its dilatancy angle. Finally, the volumetric and shear strains of the shear band were computed for two limiting initial thicknesses of the shear band corresponding to 1 mm and 1.5 mm. The computed meso scale strains are several times larger than those reported in sand
