Single-particle limit of a topological edge state in a locally resonant band gap
Garigipati Sai Srikanth, Kai Qian, Ian Frankel +3
Topological metamaterials promise unprecedented wave control. Here, we theoretically and numerically investigate a one-dimensional Su-Schrieffer-Heeger (SSH)-inspired stiffness dim…
Electric-Field-Controlled Chemical Reaction via Piezo-Chemistry Creates Programmable Material Stiffness
Jun Wang, Zhao Wang, Jorge Ayarza +12
The spatial and temporal control of material properties at a distance has yielded many unique innovations including photo-patterning, 3D-printing, and architected material design.…
Minimizing finite viscosity enhances relative kinetic energy absorption in bistable mechanical metamaterials but only with sufficiently fine discretization: a nonlinear dynamical size effect
Haning Xiu, Ryan Fancher, Ian Frankel +4
Bistable mechanical metamaterials have shown promise for mitigating the harmful consequences of impact by converting kinetic energy into stored strain energy, offering an alternati…
Customizable wave tailoring materials enabled by nonlinear bilevel inverse design
Brianna MacNider, Haning Xiu, Kai Qian +3
Passive transformation of waves via nonlinear systems is ubiquitous in settings ranging from acoustics to optics and electromagnetics. Passivity is of particular importance for res…
