Length Scale in Granular Media

  title={Length Scale in Granular Media},
  author={Matthew R. Kuhn and Takashi Matsushima}
The thickness of shear bands depends upon the size of the grains themselves. We consider two possible sources of this scaling: geometric and mechanical. Because each particle occupies space, particle movements are constrained by their physical size and shape and by their surface curvatures at the contacts. We call these origins “geometric.” The motions of… CONTINUE READING
