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…
Micromechanics of compressive and tensile forces in partially-bonded granular materials
Abrar Naseer, Karen E. Daniels, Tejas G. Murthy
In granular media, the presence of even small amounts of interparticle cohesion manifests as an increase in the bulk strength and stiffness, effects that are typically associated w…
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…
Extracting Contact Forces in Cohesive Granular Ensembles
Abrar Naseer, Karen E. Daniels, Tejas G. Murthy
Interparticle cohesion is prevalent in stored powders, geological formations, and infrastructure engineering, yet a comprehensive understanding of the effects of its micro-mechanic…
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…
Sound propagation and force chains in granular materials
Eli T. Owens, Karen E. Daniels
Granular materials are inherently heterogeneous, leading to challenges in formulating accurate models of sound propagation. In order to quantify acoustic responses in space and tim…
