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) rheolo…
Competition between Glassy Five-Fold Structures and Locally Dense Packing Structures Governs Two-Stage Compaction of Granular Hexapods
Rudan Luo, Houfei Yuan, Yi Xing +9
Using X-ray tomography, we experimentally investigate the structural evolution of packings composed of 3D-printed hexapod particles, each formed by three mutually orthogonal sphero…
Critical evaluations of different implementations of Edwards volume ensemble
Houfei Yuan, Yujie Wang
Granular systems can display reproducible microscopic distributions governed by a few macroscopic parameters, parallel to equilibrium statistical mechanics. Building on this analog…
Compaction of Granular Columns under Thermal Cycling
Yuxuan Luo, Haiyang Lu, Xinyu Ai +5
Granular materials undergo compaction under periodic temperature fluctuations, leading to various engineering and geological phenomena from landslides to silo compaction. Although…
