Analysis of thermoelastic laminated Timoshenko beam with time-varying delay

Partial Differential Equations in Applied Mathematics
This document presents a study into a linear thermoelastic laminated Timoshenko beam featuring a time-varying delay. Utilizing the semigroup method and the variable norm technique, we establish the well-posedness of the system.

STABILIZATION FOR THE TRANSMISSION PROBLEM OF THE TIMOSHENKO SYSTEM IN THERMOELASTICITY WITH TWO CONCENTRATED MASSES

, 2019
In this paper, our main goal is to study the stability of the ther-moelastic Timoshenko beam with locally distributed temperature. Then, we consider the transmission problem of the Timoshenko system in thermoelas-ticity with two concentrated masses.

Exponential stability for Timoshenko model with thermal effect

summary:We performe an exponential decay analysis for a Timoshenko-type system under the thermal effect by constructing the Lyapunov functional. More precisely, this thermal effect is acting as a mechanism for dissipating energy generated by the bending ...

THE CRITICAL LOAD PARAMETER OF A TIMOSHENKO BEAM WITH ONE-STEP CHANGE IN CROSS SECTION

Facta Universitatis. Series: Mechanical Engineering, 2014
The paper analyzes the transverse vibration of a Timoshenko beam with one-step change in cross-section when subjected to an axial force. The axial force is equal in both of the beam portions.

Well-posedness and exponential stability for a linear damped Timoshenko system with second sound and internal distributed delay

Electronic Journal of Differential Equations, 2014
In this article we consider one-dimensional linear thermoelastic system of Timoshenko type with linear frictional damping and a distributed delay acting on the displacement equation. The heat flux of the system is governed by Cattaneo's law.

Shape optimization of a Timoshenko beam together with an elastic foundation

Applied and Computational Mechanics, 2010
In this article we are going first to aim at the variational ormulation of the bending problem for the Timoshenko beam model. Afterwards we will extend this problem to the Timoshenko beam resting on the Winkler foundation, which is firmly connected with

Exponential Decay and Numerical Solution for a Timoshenko System with Delay Term in the Internal Feedback

International Journal of Analysis and Applications, 2013
In this work we study the asymptotic behavior as t → ∞ of the solution for the Timoshenko system with delay term in the feedback. We use the semigroup theory for to prove the well-posedness of the system and for to establish the exponential stability. As
