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 ...

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

Advanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

Asymptotic behavior of solutions of a viscoelastic Shear beam model with no rotary inertia: General and optimal decay results

Open Mathematics
In this study, we consider a viscoelastic Shear beam model with no rotary inertia. Specifically, we study ρ1φtt−κ(φx+ψ)x+(g∗φxx)(t)=0,−bψxx+κ(φx+ψ)=0,\begin{array}{rcl}{\rho }_{1}{\varphi }_{tt}-\kappa {\left({\varphi }_{x}+\psi )}_{x}+\left(g\ast ...

Dynamic Stiffness Matrix for a Beam Element with Shear Deformation

Shock and Vibration, 1995
A method for calculating the dynamic transfer and stiffness matrices for a straight Timoshenko shear beam is presented. The method is applicable to beams with arbitrarily shaped cross sections and places no restrictions on the orientation of the element ...

Stability of Timoshenko systems with past history

Journal of Mathematical Analysis and Applications, 2008
The paper deals with linear one-dimensional integro-differential vibrating systems of the Timoshenko type with past history acting only in one equation. The authors show that the dissipation given by the history term is strong enough to produce the exponential stability of the considered systems if and only if the equations have the same wave speeds ...

A New Perspective on the Energy Decay of the Timoshenko–Ehrenfest System: The Non-Local Truncated Approach

Mathematics
This paper presents a new perspective on the energy decay of a nonlocal truncated Timoshenko–Ehrenfest system. By using the non local elasticity theory, this model is a generalization of the standard truncated Timoshenko system. The well-posedness of the

B\'{e}zier $\bar{B}$ Projection

, 2018
In this paper we demonstrate the use of B\'{e}zier projection to alleviate locking phenomena in structural mechanics applications of isogeometric analysis. Interpreting the well-known $\bar{B}$ projection in two different ways we develop two formulations
