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.

A transmission problem for the Timoshenko system with one local Kelvin–Voigt damping and non-smooth coefficient at the interface [PDF]

Computational and Applied Mathematics, 2020
In this paper, we study the indirect stability of Timoshenko system with local or global Kelvin–Voigt damping, under fully Dirichlet or mixed boundary conditions. Unlike Zhao et al.

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.

Global stability for damped Timoshenko systems

Discrete & Continuous Dynamical Systems - A, 2003
A mixed problem for a nonlinear one-dimensional Timoshenko system is studied. In the special linear case, sufficient and necessary conditions are given which guarantee the exponential stability. In more general linear case, the polynomial decay and in the nonlinear case the exponential decay of small solutions are proved.

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.

On the stability of Bresse and Timoshenko systems with hyperbolic heat conduction [PDF]

Journal of Differential Equations, 2021
We investigate the stability of three thermoelastic beam systems with hyperbolic heat conduction. First, we study the Bresse-Gurtin-Pipkin system, providing a necessary and sufficient condition for the exponential stability and the optimal polynomial decay rate when the condition is violated.

Conservative Semidiscrete Difference Schemes for Timoshenko Systems [PDF]

Journal of Applied Mathematics, 2014
We present a parameterized family of finite-difference schemes to analyze the energy properties for linearly elastic constant-coefficient Timoshenko systems considering shear deformation and rotatory inertia. We derive numerical energies showing the positivity, and the energy conservation property and we show how to avoid a numerical anomaly known as ...

The optimal polynomial decay in the extensible Timoshenko system

Mathematische Nachrichten
In this paper, we derive the equations that constitute the nonlinear mathematical model of an extensible thermoelastic Timoshenko system. The nonlinear governing equations are derived by applying the Hamilton principle to full von Kármán equations.

Sensing linear viscoelastic constitutive parameters with a Timoshenko beam on a multi-layer foundation: Modeling and simulation

Sensing and Bio-Sensing Research, 2015
We present a sensor model comprised of a Timoshenko beam coupled with a linear viscoelastic substrate via a distributed system of compliant elements. The system of governing equations includes the evolution of the kinematic descriptors of the Timoshenko ...

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 ...
