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…
Memory Effects in Granular Material
Christophe Josserand, Alexei Tkachenko, Daniel M. Mueth +1
We present a combined experimental and theoretical study of memory effects in vibration-induced compaction of granular materials. In particular, the response of the system to an ab…
Compaction of Rods: Relaxation and Ordering in Vibrated, Anisotropic Granular Material
Fernando X. Villarruel, Benjamin E. Lauderdale, Daniel M. Mueth +1
We report on experiments to measure the temporal and spatial evolution of packing arrangements of anisotropic, cylindrical granular material, using high-resolution capacitive monit…
