Statistical equivalence of reduced gravity and enhanced friction in granular packings
Haiyang Lu, Zhikun Zeng, Houfei Yuan +5
Using X-ray tomography, we compare granular packings prepared under buoyancy-reduced effective gravity with normal gravity packings of particles with systematically varied friction…
A Unified Glassy Rheology for Granular Matter
Zhikun Zeng, Jiazhao Xu, Hanyu Li +14
Granular flows are ubiquitous in nature and industrial applications, yet a complete continuum theory remains a long-standing challenge. The leading empirical approach, μ(I) rheolog…
Identifying Bridges from Asymmetric Load-Bearing Structures in Tapped Granular Packings
Chijin Zhou, Shuyang Zhang, Xueliang Dai +5
Using high-resolution x-ray tomography, we experimentally investigate the bridge structures in tapped granular packings composed of particles with varying friction coefficients. We…
Microscopic Structural Study on the Growth History of Granular Heaps Prepared by the Raining Method
Hanyu Li, Houfei Yuan, Zhikun Zeng +4
Granular heaps are critical in both industrial applications and natural processes, exhibiting complex behaviors that have sparked significant research interest. The stress dip phen…
