Abstract

We study fluctuations in the drag force resisting the motion of an object being pulled through a dense spherical granular medium. These fluctuations are stick-slip in nature due to the jamming and reorganization of the grains. The fluctuations in the force are periodic at small depths, but they become "stepped" at large depths. We interpret this transition as a consequence of the long-range nature of the force chains.
