DYNAMICS OF NONLINEAR SNAP–THROUGH CHAINS WITH APPLICATION TO ENERGY HARVESTING AND WAVE PROPAGATION By Smruti Ranjan Panigrahi There is much current research interest in nonlinear structures, smart materials, and metamaterials, that incorporate bistable, or snap-through, structural elements. Various applications include energy harvesting, energy dissipation, vibration absorption, vibration isolation, targeted energy transfer, bandgap design and metamaterials. In this dissertation, we explore…

Dynamics of periodic mechanical structures containing bistable elastic elements: from elastic to solitary wave propagation.
TLDR
The investigated nonlinear dynamics of a periodic chain of bistable elements consisting of masses connected by elastic springs whose constraint arrangement gives rise to a large-deformation snap-through instability produces three different regimes of wave propagation in the periodic medium, depending on the wave amplitude.
Energy harvesting in the super-harmonic frequency region of a twin-well oscillator
Nonlinear dynamical systems exhibit super-harmonic resonances that can activate large-amplitude motions at fraction integers of the fundamental frequency of the system. Such resonances offer a unique
Complex dynamics and targeted energy transfer in linear oscillators coupled to multi-degree-of-freedom essentially nonlinear attachments
We study the dynamics of a system of coupled linear oscillators with a multi-DOF end attachment with essential (nonlinearizable) stiffness nonlinearities. We show numerically that the multi-DOF
Bistable energy harvesting enhancement with an auxiliary linear oscillator
Recent work has indicated that linear vibrational energy harvesters with an appended degree-of-freedom (DOF) may be advantageous for introducing new dynamic forms to extend the operational bandwidth.
A review of the recent research on vibration energy harvesting via bistable systems
The investigation of the conversion of vibrational energy into electrical power has become a major field of research. In recent years, bistable energy harvesting devices have attracted significant
Efficiency of targeted energy transfers in coupled nonlinear oscillators associated with 1 : 1 resonance captures : Part II , analytical study
We study targeted energy transfer in a two degree-of-freedom damped system under the condition of 1:1 transient resonance capture. The system consists of a linear oscillator strongly coupled to an
Optimal Energy Harvesting From Low-Frequency Bistate Force Loadings
This paper considers techniques for harvesting energy from vibratory loadings that can be characterized by low-frequency alternations between a minimum and maximum force magnitude. In such cases, it
