Micro-fabric and couple stress in shear bands of granular materials
Abstract
Two shear bands, one from natural soil and the other from an artificial assembly, were studied with special interest in their micro-fabric induced by shearing deformation. Development of column-like load paths and their collapse by rotation are the most important observations to be taken into account in micromechanics of granular soils. It is inferred from these findings that couple-stress can take an important part in the formation of shear bands.
