Onset of Irreversibility in Cyclic Shear of Granular Packings
Steven Slotterback, Mitch Mailman, Krisztian Ronaszegi +3
We investigate the onset of irreversibility in a dense granular medium subjected to cyclic shear in a split-bottom geometry. To probe the micro and mesoscale we image bead trajecto…
The path to fracture in granular flows: dynamics of contact networks
Mark Herrera, Shane McCarthy, Steven Slotterback +3
Capturing the dynamics of granular flows at intermediate length scales can often be difficult. We propose studying the dynamics of contact networks as a new tool to study fracture…
From Frictional to Viscous Behavior: Three Dimensional Imaging and Rheology of Gravitational Suspensions
Joshua A. Dijksman, Elie Wandersman, Steven Slotterback +4
We probe the three dimensional flow structure and rheology of gravitational (non-density matched) suspensions for a range of driving rates in a split-bottom geometry. We establish…
Particle motion during the compaction of granular matter
Steven Slotterback, Masahiro Toiya, Leonard Goff +2
We track particle motions in a granular material subjected to compaction using a laser scattering based imaging method where compaction is achieved through thermal cycling. Particl…
