Analytical solution of two-layer beam taking into account interlayer slip and shear deformation [PDF]

open access: yes, 2007
A mathematical model is proposed and its analytical solution derived for the analysis of the geometrically and materially linear two-layer beams with different material and geometric characteristics of an individual layer.

Wave propagation characteristics in nanoporous metal foam nanobeams

open access: yesResults in Physics, 2019
This research is devoted to the wave propagation characteristics analysis of nanobeams made of nanoporous metal foams. Three nanoporosity distribution models, namely, symmetry, asymmetry and uniform distributions, are taken into account.

Vibrational Energy Flow Analysis of Corrected Flexural Waves in Timoshenko Beam – Part I: Theory of an Energetic Model

open access: yesShock and Vibration, 2006
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

A Screw Theory of Timoshenko Beams

open access: yesJournal of Applied Mechanics, 2009
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

open access: yesJournal of Ocean Engineering and Science, 2018
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 ...
