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…
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…
Data-driven Modeling of Granular Chains with Modern Koopman Theory
Atoosa Parsa, James Bagrow, Corey S. O'Hern +2
Externally driven dense packings of particles can exhibit nonlinear wave phenomena that are not described by effective medium theory or linearized approximate models. Such nontrivi…
