In this paper, an energy flow model is developed to analyze transverse vibration including the effects of rotatory inertia as well as shear distortion, which are very important in the Timoshenko beam transversely vibrating in the medium-to-high frequency

An exact dynamic stiffness matrix for a beam incorporating Rayleigh–Love and Timoshenko theories [PDF]
An exact dynamic stiffness matrix for a beam is developed by integrating the Rayleigh–Love theory for longitudinal vibration into the Timoshenko theory for bending vibration.

A Screw Theory of Timoshenko Beams
In this work, the classic theory of Timoshenko beams is revisited using screw theory. The theory of screws is familiar from robotics and the theory of mechanisms. A key feature of the screw theory is that translations and rotations are treated on an equal footing and here this means that bending, torsion, and extensions can all be considered together ...

A modeling method for vibration analysis of cracked beam with arbitrary boundary condition
This paper establishes a cracked Timoshenko beams model to investigate the vibration behavior based on the ultraspherical polynomials. Timoshenko beam theory is applied to model the free vibration analysis of the cracked beam and the numerical results ...

On the valid frequency range of Timoshenko beam theory [PDF]
Abstract The frequency equation of Timoshenko beam theory factorises for hinged–hinged end conditions, leading to a first and second spectrum of natural frequencies; the latter is largely inaccurate and can be isolated and disregarded. For the majority of other end conditions, when the frequency equation does not factorise, one may think in terms of ...
