Finite element reduced order models for nonlinear vibrations of piezoelectric layered beams with applications to NEMS [PDF]
, 2012 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 ...

Nonlinear hybrid-mode resonant forced oscillations of sagged inclined cables at avoidances [PDF]
, 2007 We investigate non-linear forced oscillations of sagged inclined cables under planar 1:1 internal resonance at avoidance. To account for frequency avoidance phenomena and associated hybrid modes actually distinguishing inclined cables from horizontal ...

Multi-frequency vortex-induced vibrations of a long tensioned beam in linear and exponential shear flows [PDF]
, 2013 The multi-frequency vortex-induced vibrations of a cylindrical tensioned beam of aspect ratio 200, free to move in the in-line and cross-flow directions within first a linearly and then an exponentially sheared current are investigated by means of direct

Vibration Mode of a Free-Free Column Subjected to Follower Forces
JSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1993 The dynamic instability of a free-free column subjected to a tangential follower force has been investigated. A suspended column, in which one end is supported by a rotational spring and the other end is free and thrusted, is proposed to simulate the dynamic instability phenomena of a portion from the nodal point to the trailing end of an accelerated ...

Effects of Damping and Reynolds Number on Vortex-Induced Vibrations [PDF]
, 2007 Vortex-induced vibrations have been studied experimentally with emphasis on damping and Reynolds number effects. Our system was an elastically-mounted rigid circular cylinder, free to oscillate only transverse to the flow direction, with very low ...

Energy Mechanisms of Free Vibrations and Resonance in Elastic Bodies
Physics, 2021 The scientific novelty of this work is determined by the rationale for the participation in transformations, along with the kinetic energy of particles, of four types of elastic energy, identified by the peculiarities of their phase changes in the ...

Energy Radiation from a Multi-Story Building [PDF]
, 2004 Damping limits the resonance of vibrating systems and thus higher anelastic damping is generally favored for engineered structures subjected to earthquake motions, because it means that a structure can dissipate a larger percentage of its energy per ...
