Spongelike Rigid Structures in Frictional Granular Packings

Physical Review Letters, 126(7).

By: K. Liu*, J. Kollmer n, K. Daniels n, J. Schwarz* & S. Henkes*

TL;DR: It is shown how rigidity emerges in experiments on sheared two-dimensional frictional granular materials by using generalizations of two methods for identifying rigid structures, the force-based dynamical matrix and the topology-based rigidity percolation. (via Semantic Scholar)

Migrating Shear Bands in Shaken Granular Matter

PHYSICAL REVIEW LETTERS, 125(4).

By: J. Kollmer n, T. Shreve*, J. Claussen, S. Gerth, M. Salamon, N. Uhlmann, M. Schroeter, T. Poeschel

TL;DR: Using x-ray radiography, it is demonstrated that the effect of dilatancy, the reduction in volume fraction occurring in sheared dense granular media, is caused by Dilatancy. (via Semantic Scholar)

Photoelastic force measurements in granular materials

REVIEW OF SCIENTIFIC INSTRUMENTS, 88(5).

By: K. Daniels n, J. Kollmer n & J. Puckett*

TL;DR: This review paper summarizes the past work using the photoelastic technique, describes the optics underlying the technique, and illustrates how it can be used to quantitatively determine the vector contact forces between particles in a 2D granular system. (via Semantic Scholar)
