Force network and topology
Any structural arrange of particles in static equilibrium contain elements that interact between them by contact forces. Hence, always is possible to define a network that characterizes its spatial distribution and the stress propagation across the system and between the bulk and the border. This type of networks is the cause of many of the phenomena introduced in silo storage, granular compaction, and granular piles. In this research line, we analyze (by introducing novel topological tools) the role played by the network topology on the resulting equilibrium states.
