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…
Gradient-based Design of Computational Granular Crystals
Atoosa Parsa, Corey S. O'Hern, Rebecca Kramer-Bottiglio +1
There is growing interest in engineering unconventional computing devices that leverage the intrinsic dynamics of physical substrates to perform fast and energy-efficient computati…
Universal Mechanical Polycomputation in Granular Matter
Atoosa Parsa, Sven Witthaus, Nidhi Pashine +3
Unconventional computing devices are increasingly of interest as they can operate in environments hostile to silicon-based electronics, or compute in ways that traditional electron…
Evolving Programmable Computational Metamaterials
Atoosa Parsa, Dong Wang, Corey S. O'Hern +3
Granular metamaterials are a promising choice for the realization of mechanical computing devices. As preliminary evidence of this, we demonstrate here how to embed Boolean logic g…
