The role of interstitial gas in determining the impact response of granular beds
John R. Royer, Bryan Conyers, Eric I. Corwin +2
We examine the impact of a solid sphere into a fine-grained granular bed. Using high-speed X-ray radiography we track both the motion of the sphere and local changes in the bed pac…

Gas-Mediated Impact Dynamics in Fine-Grained Granular Materials
John R. Royer, Eric I. Corwin, Peter J. Eng +1
Non-cohesive granular media exhibit complex responses to sudden impact that often differ from those of ordinary solids and liquids. We investigate how this response is mediated by…

Signatures of granular microstructure in dense shear flows
Daniel M. Mueth, Georges F. Debregeas, Greg S. Karczmar +3
Granular materials react to shear stresses differently than do ordinary fluids. Rather than deforming uniformly, materials such as dry sand or cohesionless powders develop shear ba…
