Transition rates for slip-avalanches in soft athermal disks under quasi-static simple shear deformations
Kuniyasu Saitoh, Norihiro Oyama, Fumiko Ogushi +1
We study slip-avalanches in two-dimensional soft athermal disks by quasi-static simulations of simple shear deformations. Sharp drops in shear stress, or slip-avalanches, are obser…
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…
Non-local effects in inhomogeneous flows of soft athermal disks
Kuniyasu Saitoh, Brian P. Tighe
We numerically investigate non-local effects on inhomogeneous flows of soft athermal disks close to but below their jamming transition. We employ molecular dynamics to simulate Kol…
Avalanche Interpretation of the Power-Law Energy Spectrum in Three-Dimensional Dense Granular Flow
Norihiro Oyama, Hideyuki Mizuno, Kuniyasu Saitoh
Turbulence is ubiquitous in nonequilibrium systems, and it has been noted that even dense granular flows exhibit characteristics that are typical of turbulent flow, such as the pow…
