International Journal of Solids and Structures, 2001
The authors study the bending of nonuniform Euler-Bernoulli and Timoshenko beams with jump discontinuities. After giving some definitions and concepts of the theory of generalized functions, the authors derive governing equilibrium equations in the space of generalized functions, and perform selected valuations.

Mathematical Modelling of Stepped Beam Energy Harvesting Using Euler–Bernoulli’s Theory
2018Energy harvesting with cantilever beam is the most commonly used method for small electrical input devices like sensors etc. Uniform cantilever beam with no concentrated mass at the end produces less energy than the beam with concentrated mass at end.

A Comparison of the Timoshenko Theory and the Euler-Bernoulli Theory for Control of Laminated Beams
Aerospace, 1996Abstract In this paper, the governing equations and boundary conditions of laminated beam smart structures are presented. Sensor and actuator layers are included in the beam so as to facilitate vibration supression. Two mathematical models are presented: the shear-deformable (Timoshenko) model and the shear-indeformable (Euler-Bernoulli)

The cantilever beams experimental dynamic investigation according to the Euler-Bernoulli theory
STUDIES IN ENGINEERING AND EXACT SCIENCESThe purpose of this study is to experimentally determine the natural frequencies by modal analysis of flexure vibrations of cantilever Euler-Bernoulli beams with different dimensions to verify this classical theory. The influence of the sensor mass and its position on the natural frequencies is subsequently determined. For this purpose, the first three

Comparison of beam finite elements based on Euler-Bernoulli beam theory
2016When finite element method is employed for ship structural response calculation, beam finite elements are used in initial design phases in order to shorten time needed for model generation as well as for response calculation itself. Problem arises in modelling interactions between plating and corresponding stiffeners.

Computation of ply thickness of laminated beam for which Euler-Bernoulli theory is adequate
Composite Structures, 1994In this paper computation of the ply thickness of laminated beam for which Euler-Bernoulli beam theory would predict the fundamental frequency within the specified degree of accuracy has been considered. It is assumed that the degree of accuracy (or the tolerance) is given a priori in addition to the depth ratio of the individual ply to the total depth

Single-beam analysis of damaged beams: Comparison using Euler–Bernoulli and Timoshenko beam theory
Journal of Sound and Vibration, 2014Abstract A new general formulation that is applicable to the damaged, linear elastic structures ‘unified framework’ is used to obtain analytical expressions for natural frequencies and mode shapes. The term mode shapes is used to mean the displacement modes, the section rotation modes, the sectional bending strain modes and sectional shear strain ...
