On the accuracy of the Timoshenko beam theory above the critical frequency: best shear coefficient [PDF]

open access: yesarXiv, 2014
We obtain values for the shear coefficient both below and above the critical frequency by comparing the results of the Timoshenko beam theory with experimental data published recently. The best results are obtained, by a least-square fitting, when different values of the shear coefficient are used below and above the critical frequency.

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

open access: goldApplied 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,

Energy approach vibration analysis of nonlocal Timoshenko beam theory

open access: goldProcedia Engineering, 2011
AbstractThe aim of this paper is to present an efficient numerical method to analyze the vibration behavior of nano Timoshenko beams based on Eringen's nonlocal elasticity theory. The vibration frequencies of beams are firstly obtained using the theorem of minimum total potential energy and Chebyshev polynomial functions. The present method provides an

A LINEARIZED TIMOSHENKO BEAM THEORY IN FINITE DISPLACEMENTS

open access: bronzeDoboku Gakkai Ronbunshu, 1985
A linearized finite displacement theory of the Timoshenko beam is formulated as the counterpart to so-called beam-column theory of the Bernoulli-Euler beam. The corresponding stiffness equation is derived in a useful form for practical applications. Both theory and stiffness equation result in the same buckling load as the Engesser formula which has ...
