Variational Derivation of Truncated Timoshenko-Ehrenfest Beam Theory [PDF]

Journal of Applied and Computational Mechanics, 2022
The beam theory allowing for rotary inertia and shear deformation and without the fourth order derivative with respect to time as well as without the slope inertia, as was developed by Elishakoff through the dynamic equilibrium consideration, is derived ...

Dynamic Response of Slope Inertia-Based Timoshenko Beam under a Moving Load

Applied Sciences, 2022
In this paper, the dynamic response of a simply supported beam subjected to a moving load is reinvestigated. Based on a new beam theory, slope inertia-based Timoshenko (SIBT), the governing equations of motion of the beam are derived.

Optimal Cantilever Dynamic Vibration Absorbers by Timoshenko Beam Theory [PDF]

Shock and Vibration, 2004
A double‐ended cantilever beam as a distributed parameter dynamic vibration absorber has been applied to a single‐degree‐of‐freedom system subjected to harmonic forces.In this investigation, the beam has been analyzed under the well known model of Timoshenko and the computation of best parameters is based on the Chebyshev’s optimality criterion.This is
