Reflection and Exclusion of Shear Zones in Inhomogeneous Granular Materials
Tamas Borzsonyi, Tamas Unger, Balazs Szabo +3
Shear localization in granular materials is studied experimentally and numerically. The system consists of two material layers with different effective frictions. The presence of t…
Collective rheology in quasi static shear flow of granular media
Tamás Unger
This paper is devoted to the basic question of what factors determine the strain field in a quasi static granular flow. It is shown that using stress - strain rate relations is not…
Shear zone refraction and deflection in layered granular materials
Tamas Borzsonyi, Tamas Unger, Balazs Szabo
Refraction and deflection of shear zones in layered granular materials was studied experimentally and numerically. We show, that (i) according to a recent theoretical prediction [T…
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…
Generation of homogeneous granular packings: Contact dynamics method with coupling to an external pressure bath
M. Reza Shaebani, Tamas Unger, Janos Kertesz
The contact dynamics method (CD) is an efficient simulation technique of dense granular media where unilateral and frictional contact problems for a large number of rigid bodies ha…
