Localized and extended dynamical correlation lengths in jammed packings of soft athermal disks under slow shear
Shoichi Takahata, Norihiro Oyama, Kuniyasu Saitoh
Dynamics of jammed packings of soft athermal disks under finite-rate shear are studied by means of molecular dynamics simulations. Particularly, we investigate the spatial structur…
Structural and mechanical characteristics of sphere packings near the jamming transition: From fully amorphous to quasi-ordered structures
Hideyuki Mizuno, Kuniyasu Saitoh, Leonardo E. Silbert
Mechanically stable sphere packings are generated in three-dimensional space using the discrete element method, which span a wide range in structural order, ranging from fully amor…
Stress relaxation above and below the jamming transition
Kuniyasu Saitoh, Takahiro Hatano, Atsushi Ikeda +1
We numerically investigate stress relaxation in soft athermal disks to reveal critical slowing down when the system approaches the jamming point. The exponents describing the diver…
Universal relaxation dynamics of sphere packings below jamming
Atsushi Ikeda, Takeshi Kawasaki, Ludovic Berthier +2
We show that non-Brownian suspensions of repulsive spheres below jamming display a slow relaxational dynamics with a characteristic time scale that diverges at jamming. This slow t…
Elastic wave propagation in dry granular media: effects of probing characteristics and stress history
Hongyang Cheng, Stefan Luding, Kuniyasu Saitoh +1
Elastic wave propagation provides a noninvasive way to probe granular materials. The discrete element method using particle configuration as input, allows a micromechanical interpr…
Rotational sound in disordered granular materials
Kuniyasu Saitoh, Rohit K. Shrivastava, Stefan Luding
We employ numerical simulations to understand the evolution of elastic standing waves in disordered frictional disk systems, where the dispersion relations of rotational sound mode…
