QMU Analysis of Flexoelectric Timoshenko Beam by Evidence Theory
Advances in Mathematical Physics, 2023 In recent years, with the rapid development of nanotechnology, a new type of electromechanical coupling effect similar to the piezoelectric effect, the flexoelectric effect, has gradually come into the public’s view. The flexoelectric beam that is the main structural unit of the flexoelectric signal output has broad application prospects in the next ...

Micropolar modeling approach for periodic sandwich beams [PDF]
Compos. Struct. 2018;185:656-664, 2018 We develop a micropolar Timoshenko beam theory and use it to model web-core sandwich beams. The beam theory is derived by a vector approach and the general displacement solution to the governing sixth-order equations is given. A nodally-exact micropolar Timoshenko beam element is formulated using the solution.

Analytical solutions for the Timoshenko beam theory with Free-Free boundary conditions [PDF]
arXiv, 2021 Timoshenko's theory for bending vibrations of a beam has been extensively studied since its development nearly one hundred years ago. Unfortunately there are not many analytical results. The results above the critical frequency inclusive haeve been tested only recently. Here an analytical expression for the solutions of the Timoshenko equation for free-

Modeling an elastic beam with piezoelectric patches by including magnetic effects [PDF]
American Control Conference Proceedings, pp. 1045-1050, 2014, 2014 Models for piezoelectric beams using Euler-Bernoulli small displacement theory predict the dynamics of slender beams at the low frequency accurately but are insufficient for beams vibrating at high frequencies or beams with low length-to-width aspect ratios. A more thorough model that includes the effects of rotational inertia and shear strain, Mindlin-

A Numerical Case Study on Contact Analysis with Large Displacement
MATEC Web of Conferences, 2016 In case of geometrically non-linear analysis of plane frame structures, Bernoulli-Euler beam elements considering the shear deformation to be zero are generally used.

Block Backstepping for Isotachic Hyperbolic PDEs and Multilayer Timoshenko Beams [PDF]
arXiv, 2023 In this paper, we investigate the rapid stabilization of N-layer Timoshenko composite beams with anti-damping and anti-stiffness at the uncontrolled boundaries. The problem of stabilization for a two-layer composite beam has been previously studied by transforming the model into a 1-D hyperbolic PIDE-ODE form and then applying backstepping to this new ...

New decay rates for a Cauchy thermelastic laminated Timoshenko problem with interfacial slip under Fourier or Cattaneo laws [PDF]
, 2021 The objective of the present paper is to investigate the decay of solutions for a laminated Timoshenko beam with interfacial slip in the whole space R subject to a thermal effect acting only on one component modelled by either Fourier or Cattaneo law. When the thermal effect is acting via the second or third component of the laminated Timoshenko beam ...
