On the stability of Timoshenko systems with Gurtin–Pipkin thermal law

Journal of Differential Equations, 2014
We analyze a differential system describing a Timoshenko beam coupled with a temperature evolution of Gurtin-Pipkin type. A necessary and sufficient condition for exponential stability is established in terms of the structural parameters of the equations.

Effective Material Stiffness in Curved Actuators

Advanced Intelligent Systems, EarlyView.
A new actuator effective material stiffness measurement method is created. It produces a new metric called shape actuation modulus with the potential to help design actuators. This method shows that the smaller the curvature of hinge‐shaped actuators, the stiffer they are.

Analysis of Critical Velocities for an Infinite Timoshenko Beam Resting on an Elastic Foundation Subjected to a Harmonic Moving Load

Shock and Vibration, 2014
Critical velocities are investigated for an infinite Timoshenko beam resting on a Winkler-type elastic foundation subjected to a harmonic moving load. The determination of critical velocities ultimately comes down to discrimination of the existence of ...

Exponential stabilty for a Timoshenko system with nonlocal delay

Trends in Computational and Applied Mathematics, 2020
The purpose of this paper is to study  the Timoshenko system with nonlocal time-delayed condition. The well-posedness is proved  by Hille-Yosida theorem.

Stability analysis of abstract systems of Timoshenko type [PDF]

Journal of Evolution Equations, 2016
We consider an abstract system of Timoshenko type $$ \begin{cases} _1{\ddot } + a A^{\frac12}(A^{\frac12} + ) =0\\ _2{\ddot } + b A + a (A^{\frac12} + ) - A^ = 0\\ _3{\dot } + c A + A^ {\dot } =0 \end{cases} $$ where the operator $A$ is strictly positive selfadjoint.

Experimental Modal Analysis‐Driven Gaussian Process Regression Modeling of Rectangular Steel Beams With Various Hole Geometries

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Understanding the dynamic behavior of structural components is crucial for optimizing performance and ensuring structural integrity. This study presents a new method that combines a systematic experimental investigation of four distinct hole geometries (circular, square, compact rectangular, and long rectangular) with varying hole counts, all ...

Decay rate of the solutions to the Cauchy problem of the Lord Shulman thermoelastic Timoshenko model with distributed delay

Demonstratio Mathematica
In this study, we address a Cauchy problem within the context of the one-dimensional Timoshenko system, incorporating a distributed delay term. The heat conduction aspect is described by the Lord-Shulman theory.

Riesz basis property of Timoshenko beams with boundary feedback control

International Journal of Mathematics and Mathematical Sciences, 2003
A Timoshenko beam equation with boundary feedback control is considered. By an abstract result on the Riesz basis generation for the discrete operators in the Hilbert spaces, we show that the closed-loop system is a Riesz system, that is, the sequence of
