Entangled granular media
Nick Gravish, Scott V. Franklin, David L. Hu +1
We study the geometrically induced cohesion of ensembles of granular "u-particles" which mechanically entangle through particle interpenetration. We vary the length-to-width ratio…
Drag induced lift in granular media
Yang Ding, Nick Gravish, Daniel I. Goldman
Laboratory experiments and numerical simulation reveal that a submerged intruder dragged horizontally at constant velocity within a granular medium experiences a lift force whose s…
Force and flow transition in plowed granular media
Nick Gravish, Paul B. Umbanhowar, Daniel I. Goldman
We use plate drag to study the response of granular media to localized forcing as a function of volume fraction, . A bifurcation in the force and flow occurs at the onset of dil…
