Micromechanical measurements of local plastic events in granular materials
Jie Zheng, Aile Sun, Jie Zhang
Understanding the relationship between micromechanics and macroscopic plastic deformation is vital for elucidating the deformation mechanism of amorphous solids, such as granular m…
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…
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…
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…
Level statistics and Anderson delocalization in two-dimensional granular materials
Ling Zhang, Yinqiao Wang, Jie Zheng +5
Contrary to the theoretical predictions that all waves in two-dimensional disordered materials are localized, Anderson localization is observed only for sufficiently high frequenci…
On the route to shear jamming, are fragile states real?
Ling Zhang, Jie Zheng, Jie Zhang
Starting from an unjammed initial state, applying shear to a granular material of a fixed packing fraction below , i.e. the isotropic jamming density of frictionless spheres c…
The origin and nature of Boson Peak: the normal mode analysis of disordered granular crystals
Ling Zhang, Jie Zheng, Jie Zhang
Despite extensive theoretical \cite{GanterPRL1998, ElliotPRL2001,SchirmacherPRL2007, TanakaNatureM2008, MonacoPNAS2009, MarruzzoSCIRP2013} and experimental studies \cite{ChumakovPR…
