Influence of Roughness on Granular Avalanches
Jie Zheng, Yi Xing, Ye Yuan +10
Combining X-ray tomography with simultaneous shear force measurement, we investigate shear-induced granular avalanches using spherical particles with different surface roughness. W…
Disorder-induced vibrational anomalies from crystalline to amorphous solids
Ling Zhang, Yinqiao Wang, Yangrui Chen +8
The origin of boson peak -- an excess of density of states over Debye's model in glassy solids -- is still under intense debate, among which some theories and experiments suggest t…
Experimental Test on Edwards Volume Ensemble of Tapped Granular Packings
Ye Yuan, Yi Xing, Jie Zheng +9
Using X-ray tomography, we experimentally investigate granular packings subject to mechanical tapping for three types of beads with different friction coefficients. We validate Edw…
X-ray tomography investigation of cyclically sheared granular materials
Yi Xing, Jie Zheng, Jindong Li +4
We perform combined X-ray tomography and shear force measurements on a cyclically sheared granular system with highly transient behaviors, and obtain the evolution of microscopic s…
Frictional Granular Matter: Protocol Dependence of Mechanical Properties
Anaël Lemaître, Chandana Mondal, Itamar Procaccia +3
Theoretical treatments of frictional granular matter often assume that it is legitimate to invoke classical elastic theory to describe its coarse-grained mechanical properties. Her…
Granular Segregation Mechanisms by Cyclic Shear
Zhifeng Li, Zhikun Zeng, Yi Xing +6
We present an X-ray tomography study of the segregation mechanisms of tracer particles in a three-dimensional cyclically sheared bi-disperse granular medium. Big tracers are dragge…
