Rigidity percolation control of the brittle-ductile transition in disordered networks
Estelle Berthier, Jonathan E. Kollmer, Silke E. Henkes +3
In ordinary solids, material disorder is known to increase the size of the process zone in which stress concentrates at the crack tip, causing a transition from localized to diffus…
Betweenness Centrality as Predictor for Forces in Granular Packings
Jonathan E. Kollmer, Karen E. Daniels
A load applied to a jammed frictional granular system will be localized into a network of force chains making inter-particle connections throughout the system. Because such systems…
Protocol-Dependence and State Variables in the Force-Moment Ensemble
Ephraim S. Bililign, Jonathan E. Kollmer, Karen E. Daniels
Stress-based ensembles incorporating temperature-like variables have been proposed as a route to an equation of state for granular materials. To test the efficacy of this approach,…
