Discrete Breathers in One-Dimensional Diatomic Granular Crystals
N. Boechler, G. Theocharis, S. Job +3
We report the experimental observation of discrete breathers in a one-dimensional diatomic granular crystal composed of compressed elastic beads that interact via Hertzian contact.…
Generation of Sound Bullets with a Nonlinear Acoustic Lens
Alessandro Spadoni, Chiara Daraio
Acoustic lenses are employed in a variety of applications, from biomedical imaging and surgery, to defense systems, but their performance is limited by their linear operational env…
Localized Breathing Modes in Granular Crystals with Defects
G. Theocharis, M. Kavousanakis, P. G. Kevrekidis +3
We investigate nonlinear localized modes at light-mass impurities in a one-dimensional, strongly-compressed chain of beads under Hertzian contacts. Focusing on the case of one or t…
Nonlinear Waves in Disordered Diatomic Granular Chains
Laurent Ponson, Nicholas Boechler, Yi Ming Lai +3
We investigate the propagation and scattering of highly nonlinear waves in disordered granular chains composed of diatomic (two-mass) units of spheres that interact via Hertzian co…
