Finite element reduced order models for nonlinear vibrations of piezoelectric layered beams with applications to NEMS [PDF]
This article presents a finite element reduced order model for the nonlinear vibrations of piezoelectric layered beams with application to NEMS. In this model, the geometrical nonlinearities are taken into account through a von Kármán nonlinear strain ...

Initial Parameter Analysis about Resonant Orbits in Earth-Moon System
The initial parameters about resonant orbits in the Earth-Moon system were investigated in this study. Resonant orbits with different ratios are obtained in the two-body problem and planar circular restricted three-body problem (i.e., PCRTBP).
