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…

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…
