Study of Thermoelastic Damping in Microstretch Thermoelastic Thin Circular Plate
Journal of Vibration Engineering & Technologies, 2020The purpose of this paper is to study detection, microstretch function, temperature distribution function and thermoelastic damping analysis due to thermal variations and stretch forces in homogeneous, isotropic microstretch, generalized thermoelastic thin circular plate. This theory is based on the Kirchho-Love plate theory assumptions.

Nonlocal Thermoelastic Damping in Microelectromechanical Resonators
Journal of Engineering Mechanics, 2009The evaluation of loss mechanisms in microscale mechanical resonators is addressed. Among various dissipation causes, thermoelastic loss is considered as a fundamental dissipation mechanism in microbeam resonators packed in a near-vacuum environment.

Thermoelastic damping in micromechanical resonators
Applied Physics Letters, 2009We show that the dominant energy loss mechanism in plate modes of a 1.5 μm thick silicon micromechanical resonator is thermoelastic damping. In situ ultra-high vacuum annealing lowers the dissipation of two neighboring resonance modes (460 and 510 kHz) at 120 K to Q−1≤5×10−7.

Thermoelastic damping in fluid-conveying microresonators
International Journal of Heat and Mass Transfer, 2016Abstract As an inherent energy dissipation mechanism, the thermoelastic damping (TED) imposes an upper limit on the quality factors of microresonators. On the basis of Hamilton principle, the governing equation of solid–liquid-thermal coupling vibration of fluid-conveying microresonator is deduced.

Thermoelastic Damping in Axially Stressed Beam
Volume 4: 20th International Conference on Design Theory and Methodology; Second International Conference on Micro- and Nanosystems, 2008Zener’s approximate expression for thermoelastic damping was first known attempt to quantify the thermoelastic damping. Recently, an exact expression of thermoelastic damping for thin unstressed beams, which is widely used, is arrived at. Further, it has been experimentally verified that application of tensile axial stress results in increase in the Q ...

Thermoelastic damping in GaAs micromechanical resonators
physica status solidi c, 2008AbstractDamping of the mechanical motion is one of the factors that limit the sensitivity of mechanical resonators. For the development of high‐sensitivity transducers, it is important to understand the damping mechanism of the resonators and minimize the damping effect.
