Structural aging of a cohesive and amorphous granular solid under cyclic loading
William Hobson-Rhoades, Douglas J Durian, Yue Fan +1
We investigate how cyclic loading evolves the structure and deformation behaviors of a granular raft composed of particles floating at an air-oil interface. The raft has a disorder…
Collective Behavior and Memory States in Flow Networks with Tunable Bistability
Lauren E. Altman, Nadia Aguilar, Douglas J. Durian +2
Multistability-induced hysteresis has been widely studied in mechanical systems, but such behavior has proven more difficult to reproduce experimentally in flow networks. Natural f…
Cornerstones are the Key Stones: Using Interpretable Machine Learning to Probe the Clogging Process in 2D Granular Hoppers
Jesse M. Hanlan, Sam Dillavou, Andrea J. Liu +1
The sudden arrest of flow by formation of a stable arch over an outlet is a unique and characteristic feature of granular materials. Previous work suggests that grains near the out…
Taut-Line Buzzers with Periodic Forcing
Jesse M. Hanlan, Douglas J. Durian
The time-dependent forcing and work per cycle required to drive sinusoidal spinning of a taut-line buzzer is analytically derived, both on and off resonance, from the nonlinear equ…
The Equation of Motion for Taut-Line Buzzers
Alexander J. Gerra, Courtney C. Jones, Sam Dillavou +4
Equations of motion are developed for the oscillatory rotation of a disk suspended between twisted strings kept under tension by a hanging mass, to which additional forces may be a…
Stochastic dynamics of granular hopper flows: a configurational mode controls the stability of clogs
David Hathcock, Sam Dillavou, Jesse M. Hanlan +2
Granular flows in small-outlet hoppers exhibit several characteristic but poorly understood behaviors: temporary clogs (pauses) where flow stops before later spontaneously restarti…
