Localized breathing modes in granular crystals with defects
One dimensional chain tight elastic beads Hertz interaction breathing pattern
2014/12/24
We study localized modes in uniform one-dimensional chains of tightly packed and uniaxially compressed elastic beads in the presence of one or two light-mass impurities. For chains composed of beads o...
Dissipative Solitary Waves in Granular Crystals
Quantitative dissipation effect a one-dimensional crystal particles
2014/12/24
We provide a quantitative characterization of dissipative effects in one-dimensional granular crystals. We use the propagation of highly nonlinear solitary waves as a diagnostic tool and develop optim...
Intrinsic energy localization through discrete gap breathers in one-dimensional diatomic granular crystals
Discrete space breathing apparatus a one-dimensional compression elastic bead chain Hertz diatomic chain heavy particles
2014/12/24
We present a systematic study of the existence and stability of discrete breathers that are spatially localized in the bulk of a one-dimensional chain of compressed elastic beads that interact via Her...
Discrete Breathers in One-Dimensional Diatomic Granular Crystals
The coupling instability discrete respirator dimensional diatomic granular crystal compression elastic beads Hertz contact
2014/12/24
We report the experimental observation of modulational instability and discrete breathers in a one-dimensional diatomic granular crystal composed of compressed elastic beads that interact via Hertzian...
