Dynamic Response of a Double-Beam System Subjected to a Harmonic Moving Load

open access: yesApplied Sciences
The dynamic behavior of a double-beam configuration subjected to a harmonic moving load was studied in this paper. The model was built to represent the wheel–track system that was composed of two infinite Timoshenko beams joined by uniformly spaced ...

Internal constraints, reactive stresses, and the Timoshenko beam theory

open access: yes, 2001
It is shown that the kinematical assumptions of the Timoshenko theory for shearable beams can be regarded as internal constraints, some involving the first, others the second deformation gradient; such constrains are thought of as maintained by reaction ...

optimization,dynamic,Timoshenko beam theory

open access: yes, 2006
Sensitivity analyses of eigensolutions and eigenfunctions of 3-D frame structures using the exact frequency equation from the transfer dynamic stiffness matrix that was derived on Timoshenko beam theory were developed in this paper.

On triply coupled vibrations of axially loaded thin-walled composite beams [PDF]

open access: yes, 2010
Free vibration of axially loaded thin-walled composite beams with arbitrary lay-ups is presented. This model is based on the classical lamination theory, and accounts for all the structural coupling coming from material anisotropy.

Chaotic Response and Bifurcation Analysis of a Timoshenko Beam with Backlash Support Subjected to Moving Masses [PDF]

open access: yesInternational Journal of Railway Research, 2014
A simply supported Timoshenko beam with an intermediate backlash is considered. The beam equations of motion are obtained based on the Timoshenko beam theory by including the dynamic effect of a moving mass travelling along the vibrating path.

Comparison of 1D and 2D solutions for a beam under transverse impact

open access: yesMATEC Web of Conferences, 2018
The problem of non-stationary vibration of an elastic beam caused by a transverse impact loading is studied in this work. In particular, two different approaches to the derivation of analytical solution of the problem are compared. The first one is based

Analysis of Complex Composite Beam by using Timoshenko Beam Theory

open access: yes, 2013
Fiber-reinforced composites, due to their high specific strength, and stiffness, which can be tailored depending on the design requirement, are fast replacing the traditional metallic structures in the weight sensitive aerospace and aircraft industries ...

Bending evaluation of quintuple-layer FG beams with sliding interactions

open access: yesVietnam Journal of Mechanics
This paper introduces a model of a quintuple-layer composite beam made of functionally graded materials (FGMs) and shear connectors. A finite element model is developed using the first-order shear deformation theory (FSDT) of Timoshenko, employing a two-

Fractional visco-elastic Timoshenko beam from elastic Euler-Bernoulli beam

open access: yes, 2014
The Euler-Bernoulli beam theory is well established in such a way that engineers are very confident with the determination of stress field or deflections of the elastic beam based on this theory.

Comparison of Different Local Unrefined Beam Theories for Bending and Nano Beams Buckling Analysis

open access: yesJournal of Materials and Engineering Structures, 2016
In this study, non unified local shear deformation theory is proposed to consider the bending and buckling of nano beams. This theory is based on the assumption that the cross-sectional and planar displacements consist of bending and shear components ...
