Gravity Governs Shear Localization in Confined Dense Granular Flows
M Reza Shaebani, János Török, Maniya Maleki +4
Prediction of flow profiles of slowly sheared granular materials is a major geophysical and industrial challenge. Understanding the role of gravity is particularly important for fu…
Stagnant Zone Formation in a 2D Bed of Circular and Elongated Grains under Penetration
Matt Harrington, Hongyi Xiao, Douglas J. Durian
When a large blunt object penetrates into a granular material, the force response exhibits an initial nonlinear relationship with depth that is widely attributed to the formation o…
Machine Learning Characterization of Structural Defects in Amorphous Packings of Dimers and Ellipses
Matt Harrington, Andrea J. Liu, Douglas J. Durian
Structural defects within amorphous packings of symmetric particles can be characterized using a machine learning approach that incorporates structure functions of radial distances…
Eliminating Stripe Artifacts in Light-Sheet Fluorescence Imaging
Seyyed Muhammad Salili, Matt Harrington, Douglas J. Durian
We report two techniques to mitigate stripe artifacts in light-sheet fluorescence imaging. The first uses an image processing algorithm called the multidirectional stripe remover (…
Anisotropic Particles Strengthen Granular Pillars under Compression
Matt Harrington, Douglas J. Durian
We probe the effects of particle shape on the global and local behavior of a two-dimensional granular pillar, acting as a proxy for a disordered solid, under uniaxial compression.…
Granular Dynamics during Impact
Kerstin Nordstrom, Emily Lim, Matthew Harrington +1
We study the impact of a projectile onto a bed of 3 mm grains immersed in an index-matched fluid. Specifically, we vary the amount of prestrain on the sample, strengthening the for…
Suppression and emergence of granular segregation under cyclic shear
Matt Harrington, Joost H. Weijs, Wolfgang Losert
While convective flows are implicated in many granular segregation processes, the associated particle-scale rearrangements are not well understood. A three-dimensional bidisperse m…
Consequences of Anomalous Diffusion in Disordered Systems Under Cyclic Forcing
Mitch Mailman, Michelle Girvan, Wolfgang Losert
We use numerical simulations to study the behavior of 2D frictionless disk systems under cyclic shear as a function of reversal amplitude γ_r. Our studies focus on mean bulk and di…
