A Refined Zigzag Beam Theory for Composite and Sandwich Beams [PDF]

open access: yes, 2009
A new refined theory for laminated composite and sandwich beams that contains the kinematics of the Timoshenko Beam Theory as a proper baseline subset is presented.

Size effects on free vibration of heterogeneous beams

open access: yesMATEC Web of Conferences, 2018
In this paper the influence of microstructure on the free vibration of geometrically similar heterogeneous beams with free-free boundary conditions was numerically investigated by detailed finite element analysis (FEA) to identify and quantify any effect

Generalized Multi-Symplectic Numerical Implementation of Dynamic Responses for Saturated Poroelastic Timoshenko Beam

open access: yesXibei Gongye Daxue Xuebao, 2020
Based on the porous media theory and Timoshenko beam theory, properties of dynamic responses in fluid-solid coupled incompressible saturated poroelastic Timoshenko beam are investigated by generalized multi-symplectic method.

Timoshenko Beam Model for Lateral Vibration of Liquid-Phase Microcantilever-Based Sensors [PDF]

open access: yes, 2013
Dynamic-mode microcantilever-based devices are potentially well suited to biological and chemical sensing applications. However, when these applications involve liquid-phase detection, fluid-induced dissipative forces can significantly impair device ...

Comparison of theoretical calculated deflections according to the Euler-Bernoulli andЕymoshenko beam models with experimentally obtained

open access: yesБудівельні конструкції: Теорія і практика
The article presents the results of an experimental and theoretical study of the prediction of deflections of timber beams made of three types of wood: massive, glued laminated, and cross-laminated timber.

Free vibration of axially loaded multi-cracked Timoshenko beams

open access: yesMagazine of Civil Engineering, 2020
In this paper, the free vibration of axially-loaded, multi-cracked Timoshenko beams with differing boundary conditions, namely, hinged-hinged, fixed-fixed, fixed-hinged, and fixed-free is studied.

The second spectrum of Timoshenko beam theory—Further assessment [PDF]

open access: yesJournal of Sound and Vibration, 2006
A review of contributions and views on the second spectrum of Timoshenko beam theory (TBT) over the past two decades, together with some new results, are presented. It is shown that the Timoshenko frequency equation factorises not solely for hinged–hinged end conditions, as is often claimed, but also for guided–guided and guided–hinged; these new cases

Vibration Characteristics of Piezoelectric Microbeams Based on the Modified Couple Stress Theory

open access: yesShock and Vibration, 2014
The vibration behavior of piezoelectric microbeams is studied on the basis of the modified couple stress theory. The governing equations of motion and boundary conditions for the Euler-Bernoulli and Timoshenko beam models are derived using Hamilton’s ...

Bending of geometrically nonlinear cantilever beam. Results obtained by Cosserat – Timoshenko and Kirchhoff’s rod theories

open access: yesИнженерно-строительный журнал, 2015
The problem of verification of different program suites for structural analysis has recently become an important component of the construction science. One of the most extensively used benchmark problem is a classical geometrically nonlinear problem of ...

Dynamic Analysis of a Fiber-Reinforced Composite Beam under a Moving Load by the Ritz Method

open access: yesMathematics, 2021
This paper presents the dynamic responses of a fiber-reinforced composite beam under a moving load. The Timoshenko beam theory was employed to analyze the kinematics of the composite beam.
