Nonlinear vibration energy harvesting by intentional excitation of high-frequency dynamical instability
In this thesis, a vibration-based energy harvesting system utilizing essential (nonlinearizable) nonlinearities and various electromechanical coupling elements is investigated. These elements include electromagnetic and piezoelectric methods of energy conversion. The mechanical system of interest …

Stability enhancement of a transonic wing using a passive nonlinear energy sink
This study examined the use of targeted energy transfer (TET) as a mechanism for passive mitigation of transonic aeroelastic instabilities of a wind-tunnel model wing. Medium- and high-fidelity computational aeroelastic models were used to study the transonic aeroelastic instabilities of the wing …

Vortex-induced vibration of a linearly-sprung cylinder with nonlinear energy sinks
… the effect of coupling an essentially nonlinear and dissipative attachment to a linearly-sprung circular cylinder undergoing rectilinear vortex-induced vibration (VIV) normal to the mean flow. The attachment is a nonlinear energy sink (NES). The essentially nonlinear coupling between …

High amplitude response behavior of a linear oscillator-nonlinear absorber system: Identification, analysis, and attenuation by using a semi-active absorber in series
… not robust to the effects of detuning. Strongly nonlinear tuned mass dampers (NTMDs) are capable of wide-band, irreversible energy transfer known as "energy pumping" but can also exhibit high amplitude solutions which significantly amplify the response of the primary structure. Semi-active tuned …
