(2004): Investigations of shear banding in an anisotropic hypoplastic material
Int. Journal of Solids and Structures, 41, 5903-5919 FullText FullText_BOKU

Abstract:
This paper focuses on the analysis of shear band formation in a cohesionless and initially transversely isotropic granular material based on a hypoplastic continuum approach. The constitutive equation for the evolution of the stress is formulated with a non-linear tensor-valued function depending on the current void ratio, the Cauchy stress, the rate of deformation and a structure tensor for anisotropy effects. The possibility of shear band formation in biaxial, plane strain compression is analyzed and the sensitivity of the shear band orientation to the slenderness of the specimen is discussed.
