Demonstration of dispersive rarefaction shocks in hollow elliptical cylinder chains
H. Kim, E. Kim, C. Chong +2
We report an experimental and numerical demonstration of dispersive rarefaction shocks (DRS) in a 3D-printed soft chain of hollow elliptical cylinders. We find that, in contrast to…
Extreme control of impulse transmission by cylinder-based nonlinear phononic crystals
Rajesh Chaunsali, Matthew Toles, Jinkyu Yang +1
We present a novel device that can offer two extremes of elastic wave propagation --- nearly complete transmission and strong attenuation under impulse excitation. The mechanism of…
Scattering of Waves by Impurities in Precompressed Granular Chains
Alejandro J. Martínez, Hiromi Yasuda, Eunho Kim +3
We study scattering of waves by impurities in strongly precompressed granular chains. We explore the linear scattering of plane waves and identify a closed-form expression for the…
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…
