Starting to move through a granular medium
D. J. Costantino, T. J. Scheidemantel, M. B. Stone +5
We explore the process of initiating motion through a granular medium by measuring the force required to push a flat circular plate upward from underneath the medium. In contrast t…
Flux through a hole from a shaken granular medium
K. Chen, M. B. Stone, R. Barry +7
We have measured the flux of grains from a hole in the bottom of a shaken container of grains. We find that the peak velocity of the vibration, vmax, controls the flux, i.e., the f…
Studies of local jamming via penetration of a granular medium
M. B. Stone, R. Barry, D. P. Bernstein +3
We present a series of measurements examining the penetration force required to push a flat plate vertically through a dense granular medium, focusing in particular on the effects…
Avalanche Dynamics in Wet Granular Materials
P. Tegzes, T. Vicsek, P. Schiffer
We have studied the dynamics of avalanching wet granular media in a rotating drum apparatus. Quantitative measurements of the flow velocity and the granular flux during avalanches…
Granular Drag on a Discrete Object: Shape Effects on Jamming
I. Albert, J. G. Sample, A. J. Morss +3
We study the drag force on discrete objects with circular cross section moving slowly through a spherical granular medium. Variations in the geometry of the dragged object change t…
Stick-Slip Fluctuations in Granular Drag
I. Albert, P. Tegzes, R. Albert +4
We study fluctuations in the drag force experienced by an object moving through a granular medium. The successive formation and collapse of jammed states give a stick-slip nature t…
