Including nonlinearity can lead to fascinating wave propagation behavior in phononic
crystals, broadening their possible applications in acoustic engineering. The current work …

The effects of high-frequency parametric excitation on the principal parametric resonance of
a nonlinear beam are studied both theoretically and experimentally. Only the first mode of …

Parametrically excited energy harvesters provide a valuable alternative to directly excited
ones. However, linear energy harvesters subjected to parametric excitation usually suffer …

The recent trend of using thin micro-plate structures in severe operational conditions caused
the classical theory (CT) to be no longer suited in analyzing the dynamic characteristics of …

Previously, the mechanism of the magnetic rolling pendulum (MRP) has been employed in
energy harvesting, attributed to its minimal mechanical loss. However, there has been a lack …

Background The presence of parametric excitation in dynamic structures, caused by friction,
crack, varying compliance, electromagnetic field, etc. may generate unbounded responses …

In this paper, the output power map of a nonlinear energy harvester (PEH) made of a
console beam and the membrane of a resonant vibration speaker is analyzed …

This paper investigates the coupled mechanics of a fluid-conveying microtube embedded
inside an elastic medium and subject to a pretension. The fluid-structure interaction model of …

Nonlinearity exists widely in civil engineering structures; for example, the initiation and
growth of damage under dynamic loadings is a typical nonlinear process. To date, for the …
