Photoelastic Grain Solver v2.0: An updated tool for analysis of force measurements in granular materials
Carmen L. Lee, Lori McCabe, Ben McMillan +6
Photoelastic force imaging is an experimental technique whereby a birefringent granular material is imaged with a polariscope to characterize the internal stress state of a granula…
Properties of packings and dispersions of superellipse sector particles
John Colt, Lucas Nelson, Sykes Cargile +2
Superellipse sector particles (SeSPs) are segments of superelliptical curves that form a tunable set of hard-particle shapes for granular and colloidal systems. SeSPs allow for con…
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…
The Excluded Area of Superellipse Sector Particles
Kellianne Kornick, Ted Brzinski, Scott V. Franklin
Superellipse sector particles (SeSPs) are segments of superelliptical curves that form a tunable set of hard-particle shapes for granular and colloidal systems. SeSPs allow for con…
Enlightening force chains: a review of photoelasticimetry in granular matter
Aghil Abed Zadeh, Jonathan Barés, Theodore A. Brzinski +10
A photoelastic material will reveal its internal stresses when observed through polarizing filters. This eye-catching property has enlightened our understanding of granular materia…
The Hindered Settling Function at Low Re Has Two Branches
T. A. Brzinski, D. J. Durian
We analyze hindered settling speed versus volume fraction for dispersions of monodisperse spherical particles sedimenting under gravity, using data from 15 different studies dr…
Sounds of Failure: Passive Acoustic Measurements of Excited Vibrational Modes
Theodore A. Brzinski, Karen E. Daniels
Granular materials can fail through spontaneous events like earthquakes or brittle fracture. However, measurements and analytic models which forecast failure in this class of mater…
Penetration depth scaling for impact into wet granular packings
Theodore A. Brzinski, Jorin Schug, Kelly Mao +1
We present experimental measurements of penetration depths for the impact of spheres into wetted granular media. We observe that the penetration depth in the liquid saturated case…
Depth-dependent resistance of granular media to vertical penetration
T. A. Brzinski, P. Mayor, D. J. Durian
We measure the quasi-static friction force acting on intruders moving downwards into a granular medium. By utilizing different intruder geometries, we demonstrate that the force ac…
Characterization of the Drag Force in an Air-Moderated Granular Bed
Theodore A Brzinski, Douglas J Durian
We measure the torque acting on a rod rotated perpendicular to its axis in a granular bed, through which an upflow of gas is utilized to tune the hydrostatic loading between grains…
