Evolution of shear zones in granular packings under pressure
Mahnoush Madani, Maniya Maleki, János Török +1
Stress transmission in realistic granular media often occurs under external load and in the presence of boundary slip. We investigate shear localization in a split-bottom Couette c…
Flow in an hourglass: particle friction and stiffness matter
Tivadar Pongó, Viktória Stiga, János Török +5
Granular flow out of a silo is studied experimentally and numerically. The time evolution of the discharge rate as well as the normal force (apparent weight) at the bottom of the c…
Shear induced alignment and dynamics of elongated granular particles
Tamas Borzsonyi, Balazs Szabo, Sandra Wegner +5
The alignment, ordering and rotation of elongated granular particles was studied in shear flow. The time evolution of the orientation of a large number of particles was monitored i…
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…
