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.

About the stability to Timoshenko system with pointwise dissipation
Discrete & Continuous Dynamical Systems - S, 2022 In this paper we study the Timoshenko model over the interval \begin{document}$ (0, \ell) $\end{document} with pointwise dissipation at \begin{document}$ \xi\in (0, \ell) $\end{document}. We prove that this dissipation produces exponential stability when

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 MindlinâTimoshenko system when the modulus of elasticity in shear k tends to infinity, provided a regularizing term through a fourth-order ...

Exponential Stability for a Nonlinear Timoshenko System with Distributed Delay
International Journal of Analysis and Applications, 2021 . This paper is concerned with a nonlinear Timoshenko system modeling clamped thin elastic beams with distributed delay time. The distributed delay is defined on feedback term associated to the equation for rotation angle.

Nonlinear boundary stabilization for Timoshenko beam system
Journal of Mathematical Analysis and Applications, 2015 This paper is concerned with the existence and decay of solutions of the following Timoshenko system: $$ \left\|\begin{array}{cc} u"- (t) u+ _1 \displaystyle\sum_{i=1}^{n}\frac{\partial v}{\partial x_{i}}=0,\, \in \times (0, \infty),\\ v"- v- _2 \displaystyle\sum_{i=1}^{n}\frac{\partial u}{\partial x_{i}}=0, \, \in \times (0, \infty), \end ...

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.
