Mechanisms for impulsive energy dissipation and small scale effects in micro-granular media
Jonathan Bunyan, Alexander F. Vakakis, Sameh Tawfick
We study impulse response in 1-D homogeneous micro-granular chains on a linear elastic substrate. Micro-granular interactions are analytically described by the Schwarz contact mode…
Nonlinear Resonances and Antiresonances of a Forced Sonic Vacuum
D. Pozharskiy, Y. Zhang, M. O. Williams +4
We consider a harmonically driven acoustic medium in the form of a (finite length) highly nonlinear granular crystal with an amplitude and frequency dependent boundary drive. Remar…
Accelerating oscillatory fronts in a nonlinear sonic vacuum with strong non-local effects
O. V. Gendelman, V. Zolotarevskiy, A. V. Savin +2
In this Letter we describe a novel class of dynamical excitations -- accelerating oscillatory fronts in a new genre of nonlinear sonic vacua with strongly non-local effects. Indeed…
Nonlinear Low-to-High Frequency Energy Cascades in Diatomic Granular Crystals
E. Kim, R. Chaunsali, H. Xu +4
We study wave propagation in strongly nonlinear 1D diatomic granular crystals under an impact load. Depending on the mass ratio of the `light' to `heavy' beads, this system exhibit…
