Effect of sub-critical fluid shear flow on granular bed strength
Dong Wang, Sophie Bodek, Nicholas T. Ouellette +2
Interactions between fluids and granular materials are prevalent on the Earth's surface. In the case of fluid flow over a sediment bed, the fluid imparts a shear stress to the gran…
Preserving elastic anisotropy with tessellations of granular packings
Annie Z. Xia, Dong Wang, Catherine La Riviere +3
Multiscale periodic metamaterials have been designed for numerous applications, such as impact absorption, acoustic cloaking, photonic band gaps, and mechanical logic gates. This p…
Particle-scale origin of quadrupolar non-affine displacement fields in granular solids
Evan P. Willmarth, Weiwei Jin, Dong Wang +4
In this work, we identify the local structural defects that control the non-affine displacement fields in jammed disk packings subjected to athermal, quasistatic (AQS) simple shear…
Evolution of Adaptive Force Chains in Reconfigurable Granular Metamaterials
Sven Witthaus, Atoosa Parsa, Dong Wang +7
Under an externally applied load, granular packings form force chains that depend on the contact network and moduli of the grains. In this work, we investigate packings of variable…
Tuning the Size and Stiffness of Inflatable Particles
Nidhi Pashine, Dong Wang, Robert Baines +4
We describe size-varying cylindrical particles made from silicone elastomers that can serve as building blocks for robotic granular materials. The particle size variation, which is…
