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…
Electrical Transport in Tunably-Disordered Metamaterials
Caitlyn Obrero, Mastawal Tirfe, Carmen Lee +4
Naturally occurring materials are often disordered, with their bulk properties being challenging to predict from the structure, due to the lack of underlying crystalline axes. In t…
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…
Particle scale anisotropy controls bulk properties in sheared granular materials
Carmen L. Lee, Ephraim Bililign, Emilien Azéma +1
The bulk dynamics of dense granular materials arise through a combination of particle-scale and mesoscale effects. Theoretical and numerical studies have shown that collective effe…
