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

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 ...

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 $(

Dynamic Euler-Bernoulli Beam Equation: Classification and Reductions [PDF]
Mathematical Problems in Engineering, 2015 We study a dynamic fourth-order Euler-Bernoulli partial differential equation having a constant elastic modulus and area moment of inertia, a variable lineal mass densityg(x), and the applied load denoted byf(u), a function of transverse displacementu(t,x).
