The Influence of Mass on Dynamic Response of Cracked Timoshenko Beam with Restrained End Conditions: The Truncated Theory

Applied Mechanics
In this paper, the dynamic response of the Timoshenko cracked beam subjected to a mass is investigated. In turn, it is assumed that the beam has its ends restrained with both transverse and rotational elastic springs. Based on an alternative beam theory,

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 ...

QMU Analysis of Flexoelectric Timoshenko Beam by Evidence Theory [PDF]

Advances in Mathematical Physics, 2023
In recent years, with the rapid development of nanotechnology, a new type of electromechanical coupling effect similar to the piezoelectric effect, the flexoelectric effect, has gradually come into the public’s view. The flexoelectric beam that is the main structural unit of the flexoelectric signal output has broad application prospects in the next ...

Further Insights Into the Timoshenko–Ehrenfest Beam Theory

Volume 5: Dynamics, Vibration, and Control, 2022
Abstract In this paper, the theory of a Timoshenko-Ehrenfest beam is revisited and given a new perspective with particular emphasis on the relative significances of the parameters underlying the theory. The investigation is intended to broaden the scope and applicability of the theory.

Vibration Analysis of Multilink Manipulators Based on Timoshenko Beam Theory [PDF]

Journal of Robotics, 2011
Timoshenko's theory is adopted in order to accurately describe the freely vibrating dynamics of a multilink flexible manipulator. It is herein presented an analytical modelling strategy that extends previous works through a more refined model which accounts for elastic complicating effects along with lumped inertial loads which are typically mounted on
