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…
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…
Testing Adam-Gibbs relationship in tapped Granular Packings
Xinyu Ai, Houfei Yuan, Shuyang Zhang +4
Disordered granular packings share many similarities with supercooled liquids, particu-larly in the rapid increase of structural relaxation time within a narrow range of temperatur…
Experimental Study of the Nematic Transition in Granular Spherocylinder Packings under Tapping
Haitao Yu, Zhikun Zeng, Ye Yuan +3
Using x-ray tomography, we experimentally investigate the nematic transition in granular spherocylinder packings induced by tapping. Upon the validation of the Edwards ensemble fra…
Equivalence of fluctuation-dissipation and Edwards' temperature in cyclically sheared granular systems

We use X-ray tomography to investigate the translational and rotational dynamical heterogeneities of a three dimensional hard ellipsoids granular packing driven by oscillatory shea…
Granular materials flow like complex fluids
Binquan Kou, Yixin Cao, Jindong Li +7
Granular materials such as sand, powders, foams etc. are ubiquitous in our daily life, as well as in industrial and geotechnical applications. Although these disordered systems for…
Origin of Non-cubic Scaling Law in Disordered Granular Packing
Chengjie Xia, Jindong Li, Bingquan Kou +9
Recent diffraction experiments on metallic glasses have unveiled an unexpected non-cubic scaling law between density and average interatomic distance, which lead to the speculation…
The structural origin of the hard-sphere glass transition in granular packing
Chengjie Xia, Jindong Li, Yixin Cao +5
Glass transition is accompanied by a rapid growth of the structural relaxation time and a concomitant decrease of configurational entropy. It remains unclear whether the transition…
