Critical behaviors of sheared frictionless granular materials near jamming transition

摘要

Critical behaviors of sheared dense and frictionless granular materials inthe vicinity of the jamming transition are numerically investigated. From theextensive molecular dynamics simulation, we verify the validity of the scalingtheory near the jamming transition proposed by Otsuki and Hayakawa (Prog.Theor. Phys., 121, 647 (2009)). We also clarify the critical behaviors of theshear viscosity and the pair correlation function based on both a phenomenologyand the simulation.
