Extent of force indeterminacy in packings of frictional rigid disks
M. Reza Shaebani, Tamas Unger, Janos Kertesz
Static packings of frictional rigid particles are investigated by means of discrete element simulations. We explore the ensemble of allowed force realizations in the space of conta…
Unjamming due to local perturbations in granular packings with and without gravity
M. Reza Shaebani, Tamas Unger, Janos Kertesz
We investigate the unjamming response of disordered packings of frictional hard disks with the help of computer simulations. First, we generate jammed configurations of the disks a…
Unjamming of Granular Packings due to Local Perturbations: Stability and Decay of Displacements
M. Reza Shaebani, Tamas Unger, Janos Kertesz
We study the mechanical response generated by local deformations in jammed packings of rigid disks. Based on discrete element simulations we determine the critical force of the loc…
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…
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…
Piling and avalanches of magnetized particles
S. Fazekas, J. Kertész, D. E. Wolf
We performed computer simulations based on a two-dimensional Distinct Element Method to study granular systems of magnetized spherical particles. We measured the angle of repose an…
