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 ...

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 ...

Nonlinear damping effects for the 2D Mindlin-Timoshenko system [PDF]
arXiv, 2021 We study in this article the asymptotic behavior of the Mindlin-Timoshenko system subject to a nonlinear dissipation acting only on the equations of the rotation angles. First, we briefly recall the existence of the solution of this system. Then, we prove that the energy associated with the Mindlin-Timoshenko system fulfills a dissipation relationship ...

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 ...

Rapid Stabilization of Timoshenko Beam by PDE Backstepping [PDF]
arXiv, 2022 In this paper, we present a rapid boundary stabilization of a Timoshenko beam with anti-damping and anti-stiffness at the uncontrolled boundary, by using PDE backstepping. We introduce a transformation to map the Timoshenko beam states into a (2+2) x (2+2) hyperbolic PIDE-ODE system.

A new perspective of exponential stability for Timoshenko systems under history and thermal effects [PDF]
arXiv, 2021 We address a Timoshenko system with memory in the history context and thermoelasticity of type III for heat conduction. Our main goal is to prove its uniform (exponential) stability by illustrating carefully the sensitivity of the heat and history couplings on the Timoshenko system.

Controller design and stability analysis of Timoshenko beam with input delay
Journal of Hebei University of Science and Technology, 2018 In order to study the influence of input time delay on the stability of Timoshenko beam system and stabilize the Timoshenko beam system with input delay and load, by using the Backstepping method, a new controller is designed to compensate for the input ...
