Fundamental structural characteristics of planar granular assemblies: Self-organization and scaling away friction and initial state
T Matsushima, R Blumenfeld - Physical review E, 2017 - APS
The microstructural organization of a granular system is the most important determinant of its
macroscopic behavior. Here we identify the fundamental factors that determine the statistics …
