Polynomial Decay of the Energy of Solutions of the Timoshenko System with Two Boundary Fractional Dissipations

Fractal and Fractional
In this study, we examine Timoshenko systems with boundary conditions featuring two types of fractional dissipations. By applying semigroup theory, we demonstrate the existence and uniqueness of solutions.

Decaimiento Polinomial y Modelaje Numérico Computacional de la viga de Timoshenko con disipación parcial

Selecciones Matemáticas, 2018
We studied the uniform stabilization of a class of Timoshenko systems with partial dissipation of the beam. Our main result is to prove that the semigroup associated to this model has polynomial decay.

Asymptotic stability for thermodiffusion Timoshenko systems of type III

Electronic Journal of Differential Equations
In this article, we study a Timoshenko model with thermal and mass diffusion effects. Heat and mass exchange with the environment during thermodiffusion in Timoshenko beam, where the heat conduction is given by Green and Naghdi, called thermoelasticity

Physics-Informed Neural Networks for Timoshenko System with  Thermoelasticity

The main focus of this paper is to analyze the behavior of a numerical solution of the Timoshenko system coupled with Thermoelasticity and incorporating second sound effects. In order to address this target, we employ the Physics-Informed Neural Networks (PINNs) framework to derive an approximate solution for the system.

An Eringen-like model for Timoshenko nanobeams

, 2016
Timoshenko nanobeams are investigated by using a nonlocal Eringen-like constitutive law described by two material length-scale parameters. A nonlocal variational treatment, based on a new definition of the Helmholtz free energy is proposed.

Exponential decay rate for a Timoshenko beam with boundary damping

, 2004
The exponential decay rate of a Timoshenko beam system with boundary damping is studied. By asymptotically analyzing the characteristic determinant of the system, we prove that the Timoshenko beam system is a Riesz system; hence, its decay rate is ...
