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…
Experimental Measures of Affine and Non-affine Deformation in Granular Shear
Brian Utter, R. P. Behringer
Through 2D granular Couette flow experiments, we probe failure and deformation of disordered solids under shear. Shear produces smooth affine deformations in such a solid and also…
Doublon Growth in Solidification
Brian Utter, E. Bodenschatz
We present experiments on the doublon growth morphology in directional solidification. Samples used are succinonitrile with small amounts of poly(ethylene oxide), acetone, or camph…
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…
