Enlightening force chains: a review of photoelasticimetry in granular matter
Aghil Abed Zadeh, Jonathan Barés, Theodore A. Brzinski +10
A photoelastic material will reveal its internal stresses when observed through polarizing filters. This eye-catching property has enlightened our understanding of granular materia…

Seismicity in sheared granular matter
Aghil Abed Zadeh, Jonathan Barés, Joshua Socolar +1
We report on experiments investigating the dynamics of a slider that is pulled by a spring across a granular medium consisting of a vertical layer of photo-elastic disks. The motio…

Crackling to periodic dynamics in sheared granular media
Aghil Abed Zadeh, Jonathan Barés, Robert Behringer
The local and global dynamics of a sheared granular medium are studied in a model experiment as a function of several macroscopic parameters. We observe that by changing the shear…
