Geometrical Nonlinearity for a Timoshenko Beam with Flexoelectricity

Nanomaterials, 2021
The Timoshenko beam model is applied to the analysis of the flexoelectric effect for a cantilever beam under large deformations. The geometric nonlinearity with von Kármán strains is considered.

Finite Element Modeling for Buckling Analysis of Tapered Axially Functionally Graded Timoshenko Beam on Elastic Foundation [PDF]

Mechanics of Advanced Composite Structures, 2020
In this study, an efficient finite element model with two degrees of freedom per node is developed for buckling analysis of axially functionally graded (AFG) tapered Timoshenko beams resting on Winkler elastic foundation.

Asymptotics and stabilization for dynamic models of nonlinear beams; pp. 150–155 [PDF]

Proceedings of the Estonian Academy of Sciences, 2010
We prove that the von Kármán model for vibrating beams can be obtained as a singular limit of a modified Mindlin–Timoshenko system when the modulus of elasticity in shear k tends to infinity, provided a regularizing term through a fourth-order ...

General decay in a Timoshenko-type system with thermoelasticity with second sound

Advances in Nonlinear Analysis, 2015
In this article, we consider a vibrating nonlinear Timoshenko system with thermoelasticity with second sound. We discuss the well-posedness and the regularity of solutions using the semi-group theory.

Uncertainty Quantification in Modeling of Steel Structures using Timoshenko Beam [PDF]

Journal of Structural and Construction Engineering, 2019
This paper quantifies the uncertainty emanated from modeling steel structures using a Timoshenko beam. Using continuous beams to model building structures is a conventional approach in structural dynamic analyses.

Finite element model of circularly curved Timoshenko beam for in-plane vibration analysis [PDF]

FME Transactions, 2021
Curved beams are used so much in the arches and railway bridges and equipments for amusement parks. There are few reports about the curved beam with the effects of both the shear deformation and rotary inertias.
