Networks

A prominent feature of granular materials is the presence of a heterogeneous network of interparticle forces (shown in green at left). Together with network scientists Dani Bassett (U. Pennsylvania) and Mason Porter (UCLA), we are investigating how these networks control the properties of granular materials. We have quantified how the properties of the network depend on the amount of applied pressure and friction in the system, and form an important control on the acoustical transport.
