Thermoelastic damping effects are very important intrinsic losses in microelectromechanical system/nanoelectromechanical system based sensors and filters, which limit the maximum achievable quality factor. Thermoelasticity arises due to coupling between temperature field elastic of material its interaction within structure. The impacts axisymmetric non-axisymmetric vibrations, plate dimensions,...

Abstract In this paper, we investigate the decay properties of thermoelastic suspension bridges model. We prove that energy is decaying exponentially. To our knowledge, result new and method proof based on to build appropriate Lyapunov functional.

In this article we consider one-dimensional linear thermoelastic system of Timoshenko type with linear frictional damping and a distributed delay acting on the displacement equation. The heat flux of the system is governed by Cattaneo’s law. Under suitable assumption on the weight of the delay and that of frictional damping, we establish the well-posedness result and prove that the system is ex...

In previous work (Z. Angew. Math. Phys. 68(2), 2017), Apalara considered a onedimensional thermoelastic laminated beam under Cattaneo’s law of heat conduction and proved the exponential and polynomial decay results depend on the stability number χτ . In this paper, we continue to study the same system and show that the solution of the concerned system lacks of exponential decay result in the ca...

For (coupled systems of) partial differential equations for which nullcontrol is possible in arbitrarily short time, the typical blowup rate for the control cost is exponential in 1/T . It is shown how to derive this rate for a variety of systems, including the thermoelastic system with control restricted to a small patch in the domain and to a single component (thermal, displacement, or veloci...

Abstract—In this study, the thermoelastic instability (TEI) was analyzed using the finite element analysis technique. The governing dynamic and heat equations were described. Three dimensional thermomechanical analysis model of the disc brake system were created. An intermediate processor based on the staggered approached was used to exchange result data: temperature, friction contact power, no...

We study phonon-mediated dissipation mechanisms in small-scale mechanical systems in light of recent efforts to design high-Q micrometerand nanometer-scale electro-mechanical systems (MEMS and NEMS). We consider dissipation mechanisms which redistribute the energy within a resonator, such as thermoelastic damping, the Akhiezer effect, and the Landau–Rumer effect, as well as the radiation of ene...

A first step towards the development of a model for the Scanning Laser Source technique is presented, which entails an analytical formulation for the transient response of an isotropic, homogeneous, linearly elastic half-space submitted to a pulsed laser line source operating in the thermoelastic regime. The formulation takes into account optical penetration into the material and thermal diffus...
