Shear Zones in granular materials: Optimization in a self-organized random potential
J Torok, T. Unger, J. Kertesz +1
We introduce a model to describe the wide shear zones observed in modified Couette cell experiments with granular material. The model is a generalization of the recently proposed a…
Computer simulation of three dimensional shearing of granular materials: Formation of shear bands
S. Fazekas, J. Török, J. Kertész +1
We used computer simulations to study spontaneous strain localization in granular materials, as a result of symmetry breaking non-homogeneous deformations. Axisymmetric triaxial sh…
Critical packing in granular shear bands
S. Fazekas, J. Török, J. Kertész
In a realistic three-dimensional setup, we simulate the slow deformation of idealized granular media composed of spheres undergoing an axisymmetric triaxial shear test. We follow t…
Morphologies of three-dimensional shear bands in granular media
S. Fazekas, J. Torok, J. Kertesz +1
We present numerical results on spontaneous symmetry breaking strain localization in axisymmetric triaxial shear tests of granular materials. We simulated shear band formation usin…
Shear band formation in granular media as a variational problem
T. Unger, J. Torok, J. Kertesz +1
Strain in sheared dense granular material is often localized in a narrow region called shear band. Recent experiments in a modified Couette cell provided localized shear flow in th…
