Passive Vibration-Driven Locomotion
Anna Zigelman, Gilad Israel, Yizhar Or +1
We investigate a concept of passive, vibration-driven locomotion, in which a mechanical system achieves horizontal self-propulsion by resonantly harvesting energy from vertical env…
Wave Propagation in a Strongly Nonlinear Locally Resonant Granular Crystal
K. Vorotnikov, Y. Starosvetsky, G. Theocharis +1
In this work, we study the wave propagation in a recently proposed acoustic structure, the locally resonant granular crystal. This structure is composed of a one-dimensional granul…
Limiting Phase Trajectories: a new paradigm for the study of highly non-stationary processes in Nonlinear Physics
Leonid Manevitch, Agnessa Kovaleva, Yuli Starosvetsky
This Report discusses a recently developed concept of Limiting Phase Trajectories (LPTs) providing a unified description of resonant energy transport in a wide range of classical a…
Regimes of local energy pulsations in non-linear Klein-Gordon trimer: Higher dimensional analogs of limiting phase trajectories
Victor Kislovsky, Margarita Kovaleva, Yuli Starosvetsky
In the present paper we consider the dynamics of special class of modulated regimes emerging in the Klein-Gordon trimer. In particular, this study unveils the unique states of reso…
Interaction Forces Between Microfluidic Droplets in a Hele-Shaw Cell
Itai Sarig, Yuli Starosvetsky, Amir D. Gat
Various microfluidic systems, such as chemical and biological lab-on-a-chip devices, involve motion of multiple droplets within an immersing fluid in shallow micro-channels. Modeli…
Breather solutions of the discrete p-Schrödinger equation
Guillaume James, Yuli Starosvetsky
We consider the discrete p-Schrödinger (DpS) equation, which approximates small amplitude oscillations in chains of oscillators with fully-nonlinear nearest-neighbors interactions…
Evolution of the Primary Pulse in 1D Granular Crystals Subject to On-Site Perturbations: Analytical Study
Yuli Starosvetsky
Propagation of primary pulse through an un-compressed granular chain subject to external on-site perturbation is studied. Analytical procedure predicting the evolution of the prima…
Nonlinear Pulse Equi-partition in Weakly Coupled Ordered Granular Chains with no Pre-Compression
Yuli Starosvetsky, M. Arif Hasan, Alexander F. Vakakis
We report on the strongly nonlinear dynamics of an array of weakly coupled, non-compressed, parallel granular chains subject to a local initial impulse. The motion of the granules…
