Fractional Euler-Bernoulli beams: theory, numerical study and experimental validation [PDF]

European Journal of Mechanics - A/Solids, 2015
In this paper the classical Euler-Bernoulli beam (CEBB) theory is reformulated utilising fractional calculus. Such generalisation is called fractional Euler-Bernoulli beams (FEBB) and results in non-local spatial description.

Rail Joint Model Based on the Euler-Bernoulli Beam Theory

Romanian Journal of Transport Infrastructure, 2019
In this paper, a rail joint model consisting of three Euler-Bernoulli beams connected via a Winkler foundation is proposed in order to point out the influence of the joint gap length upon the stiffness of the rail joint.

Exploring the Limits of Euler–Bernoulli Theory in Micromechanics

Axioms, 2022
In this study, the limits of the Euler–Bernoulli theory in micromechanics are explored. Raman spectroscopy, which is extremely accurate and reliable, is employed to study the bending of a microbeam of a length of 191 μm.

Analytic solutions for free vibration analysis of laminated beams in three-dimensional statement [PDF]

EPJ Web of Conferences, 2019
In this research we consider free vibrations of laminated beams in terms of three-dimensional linear theory of elasticity. Analytic solutions for natural frequencies of laminated beams are obtained by using an asymptotic splitting method.

Modified beam theories for bending properties of nanowires considering surface/intrinsic effects and axial extension effect [PDF]

, 2012
Several studies of the surface effect on bending properties of a nanowire (NW) have been conducted. However, these analyses are mainly based on theoretical predictions, and there is seldom integration study in combination between theoretical predictions ...
