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…
Contact force measurements and local anisotropy in ellipses and disks
Yinqiao Wang, Jin Shang, Yujie Wang +1
Experimental measurements of contact forces are limited to spheres and disks in three and two dimensions, making the evaluation of the shape effect and universality of force distri…
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…
Critical behaviors of jamming in cyclically sheared frictional hard granular particles
Aile Sun, Yinqiao Wang, Yangrui Chen +5
In stark contrast to the jamming of frictionless hard-sphere (hard-disk if in two dimensions) packings, the critical jamming of frictional packings is much more elusive and still u…
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…
