Abstract

Granular materials (e.g., geological materials, powders and grains) when subjected to shear or compression deform through grain rearrangements. The structural topology of the grains, or fabric, can be usefully represented as a complex (contact) network whereby network nodes correspond to individual grains and network links correspond to grain contacts. Properties of each node (e.g., degree) can be calculated and throughout deformation this results in time series akin to sensor measurements for each grain in the assembly. These signals can be processed and collated into a particle property network with a corresponding community structure summarizing the relationship between each signal. Diffe..
