Jammed solids with pins: Thresholds, Force networks and Elasticity
Andy L. Zhang, Sean A. Ridout, Celia Parts +6
The role of fixed degrees of freedom in soft/granular matter systems has broad applicability and theoretical interest. Here we address questions of the geometrical role that a scaf…
Clogging in bidirectional suspension flow
Emily A. Hobbs, Alexander Christensen, Brian C. Utter
The sudden arrest of motion due to confinement is commonly observed via the clogging transition in the flow of particles through a constriction. We present results of a simple expe…
Transients in sheared granular matter
Brian Utter, R. P. Behringer
As dense granular materials are sheared, a shear band and an anisotropic force network form. The approach to steady state behavior depends on the history of the packing and the exi…
Self-diffusion in dense granular shear flows
Brian Utter, R. P. Behringer
Diffusivity is a key quantity in describing velocity fluctuations in granular materials. These fluctuations are the basis of many thermodynamic and hydrodynamic models which aim to…
Dynamics of Low Anisotropy Morphologies in Directional Solidification
B. Utter, E. Bodenschatz
We report experimental results on quasi-two-dimensional diffusion limited growth in directionally solidified succinonitrile with small amounts of poly(ethylene oxide), acetone, or…
