On a Nonhomogeneous Timoshenko System with Nonlocal Constraints

Journal of Function Spaces, 2021
Our main concern in this paper is to prove the well posedness of a nonhomogeneous Timoshenko system with two damping terms. The system is supplemented by some initial and nonlocal boundary conditions of integral type.

Stability analysis of abstract systems of Timoshenko type [PDF]

Journal of Evolution Equations, 2015
We consider an abstract system of Timoshenko type $$ \begin{cases} \rho_1{{\ddot \varphi}} + a A^{\frac12}(A^{\frac12}\varphi + \psi) =0\\ \rho_2{{\ddot \psi}} + b A \psi + a (A^{\frac12}\varphi + \psi) - \delta A^\gamma {\theta} = 0\\ \rho_3{{\dot ...

Stabilization of a linear Timoshenko system with infinite history and applications to the Timoshenko-heat systems

Electronic Journal of Differential Equations, 2012
In this article, we, first, consider a vibrating system of Timoshenko type in a one-dimensional bounded domain with an infinite history acting in the equation of the rotation angle.

Dynamics of a new thermoelastic Timoshenko system with second sound

Results in Applied Mathematics, 2021
This work studies the optimal and general stability of a thermoelastic Timoshenko system with second sound. More succinctly, under some assumptions on the parameters of the system, we derive an optimal and general decay result for the solution energy of ...

On a Singular Non local Fractional System Describing a Generalized Timoshenko System with Two Frictional Damping Terms

Fractal and Fractional, 2023
This paper concerns a nonhomogeneous singular fractional order system, with two frictional damping terms. This system can be considered as a generalization of the so-called Timoshenko system.
