High-Q Gold and Silicon Nitride Bilayer Nanostrings

, 2012
Low-mass, high-Q, silicon nitride nanostrings are at the cutting edge of nanomechanical devices for sensing applications. Here we show that the addition of a chemically functionalizable gold overlayer does not adversely affect the Q of the fundamental ...

Strong stability results for a Timoshenko system with thermoelasticity and two fractional damping terms

Boundary Value Problems
This paper investigates a Timoshenko system with two fractional damping terms acting on the transverse displacement and rotation angle equations, coupled with a thermoelastic effect governed by the Coleman–Gurtin law for heat flux.

Damping of thermoelastic structures [PDF]

, 1969
Report ascertains the effects of thermoelastic damping on the propagation of longitudinal waves in cylindrical rods. Review of results of wave propagation in unbounded elastic solids and in elastic cylinders precedes consideration of thermal modification

Dynamic Modulus and Damping of Boron, Silicon Carbide, and Alumina Fibers [PDF]

The dynamic modulus and damping capacity for boron, silicon carbide, and silicon carbide coated boron fibers were measured from-190 to 800 C. The single fiber vibration test also allowed measurement of transverse thermal conductivity for the silicon ...

Exponential stability result of thermoelastic laminated beam with microtemperatures and without thermal conductivity

Boundary Value Problems
In this work, we consider a thermoelastic laminated beam system with microtemperature effects in case of zero thermal conductivity. We prove that the dissipation due to the microtemperatures along with structural damping is strong enough to exponentially

Effects of humidity and temperature on quality factor of micro-beam resonators in atmospheric pressure and gas rarefaction

Vietnam Journal of Science, Technology and Engineering
At atmospheric pressure (p=101325 Pa), the effects of humidity and temperature on moist air become important when discussing the quality factor of micro-cantilever and micro-bridge resonators. The squeeze film damping (SFD) problem, the dominant damping

A memory-type thermoelastic laminated beam with structural damping and microtemperature effects: Well-posedness and general decay

Demonstratio Mathematica
In previous work, Fayssal considered a thermoelastic laminated beam with structural damping, where the heat conduction is given by the classical Fourier’s law and acting on both the rotation angle and the transverse displacements established an ...
