Vibration characteristics of functionally graded cylindrical shells under various boundary conditions
TL;DR: In this article, the vibration of a functionally graded cylindrical shell made up of stainless steel and zirconia is studied and its properties are graded in the thickness direction of the shell according to volume fraction power law distribution.

Modal identification of simple structures with high-speed video using motion magnification
TL;DR: In this article, motion magnification has been developed for visualizing exaggerated versions of small displacements with an extension of the methodology to obtain the optical flow to measure displacements, which can be extended to modal identification in structures and the measurement of structural vibrations.

The design, fabrication and evaluation of a MEMS PZT cantilever with an integrated Si proof mass for vibration energy harvesting
TL;DR: In this article, a unimorph PZT cantilever with an integrated Si proof mass, designed for low vibration frequency and high vibration amplitude environment, was designed for MEMS power generators, with an optimal resistive load of 6 kΩ from 2g (g = 9.81 m s−2) acceleration at its resonant frequency of 461.15 Hz.
Journal ArticleDOI
Piezoelectric buckled beams for random vibration energy harvesting
TL;DR: In this paper, a thin piezoelectric axially loaded beam is theoretically modelled and experimentally investigated under wideband random vibrations, and the results show that the device exhibits superior power generation over a large interval of resistive load, with gains up to more than a factor of ten compared to the unbuckled state.
