Modeling an elastic beam with piezoelectric patches by including magnetic effects
, 2014 Models for piezoelectric beams using Euler-Bernoulli small displacement theory predict the dynamics of slender beams at the low frequency accurately but are insufficient for beams vibrating at high frequencies or beams with low length-to-width aspect ...

Periodic solutions to nonlinear Euler–Bernoulli beam equations [PDF]
Communications in Mathematical Sciences, 2019 Bending vibrations of thin beams and plates may be described by nonlinear Euler-Bernoulli beam equations with $x$-dependent coefficients. In this paper we investigate existence of families of time-periodic solutions to such a model using Lyapunov-Schmidt reduction and a differentiable Nash-Moser iteration scheme. The results hold for all parameters $(

Effective filtering of modal curvatures for damage identification in beams [PDF]
, 2017 In this work, we investigate the effectiveness of a damage identification technique recently proposed in [1] and assess how it is affected by the number and position of the sensors used.

Active control of bending vibrations of Timoshenko beams using state observers
St. Petersburg Polytechnical University Journal: Physics and MathematicsWhen describing bending vibrations of elastic beams, the transition from the Bernoulli – Euler model to the Timoshenko model leads to a complication in the dynamic behavior of the beam and to the emergence of new dynamic effects and a new spectrum of ...

Kelvin-Voigt lumped parameter models for approximation of the Power-law Euler-Bernoulli beams
Alexandria Engineering Journal, 2023 The purpose of this research is to initiate an investigation of the nonlinear material strain-rate damping effects on the amplitude and frequencies of some Euler-Bernoulli Beams. It is well known that the dynamic behaviors of most heat-treated metals can
