Topological edge states and amplitude-dependent delocalization in quasiperiodic elliptically geared lattices
Shuaifeng Li, Di Zhou, Feng Li +2
We present a class of mechanical lattices based on elliptical gears with quasiperiodic modulation and geometric nonlinearity, capable of exhibiting topologically protected modes an…
Nonlinear Topological Mechanics in Elliptically Geared Isostatic Metamaterials
Fangyuan Ma, Zheng Tang, Xiaotian Shi +5
Despite the extensive studies of topological systems, the experimental characterizations of strongly nonlinear topological phases have been lagging. To address this shortcoming, we…
Elastic Weyl points and surface arc states in 3D structures
Xiaotian Shi, Rajesh Chaunsali, Feng Li +1
The study of Weyl points in electronic systems has inspired many recent researches in classical systems such as photonic and acoustic lattices. Here we show how the Weyl physics ca…
Exciting and Harvesting Vibrational States in Harmonically Driven Granular Chains
C. Chong, E. Kim, E. G. Charalampidis +6
This article explores the excitation of different vibrational states in a spatially extended dynamical system through theory and experiment. As a prototypical example, we consider…
Highly Nonlinear Wave Propagation in Elastic Woodpile Periodic Structures
E. Kim, F. Li, C. Chong +3
In the present work, we experimentally implement, numerically compute with and theoretically analyze a configuration in the form of a single column woodpile periodic structure. Our…
Damped-Driven Granular Crystals: An Ideal Playground for Dark Breathers and Multibreathers
C. Chong, F. Li, J. Yang +4
By applying an out-of-phase actuation at the boundaries of a uniform chain of granular particles, we demonstrate experimentally that time-periodic and spatially localized structure…
