On Stability of Hyperbolic Thermoelastic Reissner-Mindlin-Timoshenko Plates

, 2013
In the present article, we consider a thermoelastic plate of Reissner-Mindlin-Timoshenko type with the hyperbolic heat conduction arising from Cattaneo's law. In the absense of any additional mechanical dissipations, the system is often not even strongly

Comparison of advanced gravitational-wave detectors [PDF]

, 2001
We compare two advanced designs for gravitational-wave antennas in terms of their ability to detect two possible gravitational wave sources. Spherical, resonant mass antennas and interferometers incorporating resonant sideband extraction (RSE) were ...

Stabilization of a locally damped thermoelastic system [PDF]

Computational & Applied Mathematics, 2008
We show that the solutions of a thermoelastic system with a localized nonlinear distributed damping decay locally with an algebraic rate to zero, that is, given an arbitrary R > 0, the total energy E(t) satisfies for t > 0: E(t) < C (1 + t)-γ for regular initial data such that E(0) < R, where C and γ are positive constants. In the two-dimensional case,

Dynamics of a Micro Electrical Mechanical System Subject to Thermoelastic and Squeeze-Film Damping

MATEC Web of Conferences, 2012
The static and the dynamic behaviours of a MEMS subjected to thermoelastic and squeeze film effects have been investigated. Major attention is initially devoted to the modeling of this multi-physics system, including mechanical, electrical, thermoelastic

On the stability of a laminated beam with structural damping and Gurt–Pipkin thermal law

Nonlinear Analysis, 2021
In this paper, we investigate the stabilization of a one-dimensional thermoelastic laminated beam with structural damping coupled with a heat equation modeling an expectedly dissipative effect through heat conduction governed by Gurtin–Pipkin thermal law.

Long-Time Behavior of Quasilinear Thermoelastic Kirchhoff-Love Plates with Second Sound [PDF]

, 2018
We consider an initial-boundary-value problem for a thermoelastic Kirchhoff & Love plate, thermally insulated and simply supported on the boundary, incorporating rotational inertia and a quasilinear hypoelastic response, while the heat effects are ...

Dynamic Prediction of Deformation of Irregular Aluminum Plate Curtain Wall Structure in Gymnasium Based on Improved RBF Neural Network

Engineering Reports, Volume 8, Issue 4, April 2026.
A dynamic prediction of deformation of irregular aluminum plate curtain wall structure in the gymnasium is proposed. This method can accurately predict the deformation values of each node in the curtain wall structure, thereby identifying the main nodes that cause the instability of the curtain wall structure.
