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 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 ...

Spectral analysis and system of fundamental solutions for Timoshenko beams
Applied Mathematics Letters, 2005 AbstractWe have found a unified method to analyse Timoshenko beams under various boundary conditions that occurred in practice. Explicit asymptotic expressions for the spectrum are obtained. Our method is very simple but effective because explicit formulas are obtained for the system of fundamental solutions, which are very useful for other purposes ...
