Experimentally measuring rolling and sliding in three-dimensional dense granular packings
Zackery A. Benson, Anton Peshkov, Nicole Yunger Halpern +2
We experimentally measure a three-dimensional (3D) granular system's reversibility under cyclic compression. We image the grains using a refractive-index-matched fluid, then analyz…
Gravity Governs Shear Localization in Confined Dense Granular Flows
M Reza Shaebani, János Török, Maniya Maleki +4
Prediction of flow profiles of slowly sheared granular materials is a major geophysical and industrial challenge. Understanding the role of gravity is particularly important for fu…
Effects of interparticle friction on the response of 3D cyclically compressed granular material
Zackery Benson, Anton Peshkov, Derek C. Richardson +1
We numerically study the effect of inter-particle friction coefficient on the response to cyclical pure shear of spherical particles in three dimensions. We focus on the rotations…
Memory in 3D cyclically driven granular material
Zackery A. Benson, Anton Peshkov, Derek C. Richardson +1
We perform experimental and numerical studies of a granular system under cyclic-compression to investigate reversibility and memory effects. We focus on the quasi-static forcing of…
Reversibility of granular rotations and translations
Anton Peshkov, Michelle Girvan, Derek C. Richardson +1
We analyze reversibility of both displacements and rotations of spherical grains in three-dimensional compression experiments. Using transparent acrylic beads with cylindrical hole…
Coexistence and Transition between Shear Zones in Slow Granular Flows
Robabeh Moosavi, M. Reza Shaebani, Maniya Maleki +3
We report experiments on slow granular flows in a split-bottom Couette cell that show novel strain localization features. Nontrivial flow profiles have been observed which are show…
