Comparing dragonfly wings to jars of marbles through the lens of hyperuniformity
Karen E. Daniels, Charles Emmett Maher, Katherine A. Newhall +2
When we look at the world around us, we see both organized (also called ordered) and disorganized (also called disordered) arrangements of things. Carefully-tiled floors and brick…
Photoelastic Grain Solver v2.0: An updated tool for analysis of force measurements in granular materials
Carmen L. Lee, Lori McCabe, Ben McMillan +6
Photoelastic force imaging is an experimental technique whereby a birefringent granular material is imaged with a polariscope to characterize the internal stress state of a granula…
The Stress-Force-Fabric relation across shear bands
Carmen Lee, Émilien Azéma, Karen Daniels
The strength of granular materials is highly dependent on grain connectivity (fabric), force transmission, and frictional mobilization at the particle scale. Furthermore, these bul…
Loading-dependent microscale measures control bulk properties in granular material: an experimental test of the Stress-Force-Fabric relation
Carmen L. Lee, Ephraim Bililign, Emilien Azéma +1
The bulk behaviour of granular materials is tied to its mesoscale and particle-scale features: strength properties arise from the buildup of various anisotropic structures at the p…
