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…
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…
Elastic behavior in Contact Dynamics of rigid particles
Tamas Unger, Lothar Brendel, Dietrich E. Wolf +1
The systematic errors due to the practical implementation of the Contact Dynamics method for simulation of dense granular media are examined. It is shown that, using the usual iter…
Instability of the symmetric Couette-flow in a granular gas: hydrodynamic field profiles and transport
M. Sasvari, J. Kertesz, D. E. Wolf
We investigate the inelastic hard disk gas sheared by two parallel bumpy walls (Couette-flow). In our molecular dynamic simulations we found a sensitivity to the asymmetries of the…
Self-Quenched Dynamics
Janos Torok, Supriya Krishnamurthy, Janos Kertesz +1
We introduce a model for the slow relaxation of an energy landscape caused by its local interaction with a random walker whose motion is dictated by the landscape itself. By choosi…
