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…
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…
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…
Edwards thermodynamic framework controls density segregation in cyclically sheared granular materials
Haiyang Lu, Houfei Yuan, Shuyang Zhang +5
Using X-ray tomography, we experimentally investigate granular segregation phenomena in a mixture of particles with different densities under quasi-static cyclic shear. We quantita…
