Structure of force networks in tapped particulate systems of disks and pentagons I Clusters and loops
(American Physical Society, 2016)
The force network of a granular assembly, defined by the contact network and the corresponding contact
forces, carries valuable information about the state of the packing. Simple analysis of these networks based on the ...
Structure of force networks in tapped particulate systems of disks and pentagons II Persistence analysis
(American Physical Society, 2016)
In the companion paper [Pugnaloni et al., Phys. Rev. E 93, 062902 (2016)], we use classical measures based on force probability density functions (PDFs), as well as Betti numbers (quantifying the number of components, ...
