Internal friction and ultrasonic attenuation peaks associated with diffusionless phase transformations in alloys, such as thermoelastic martensites and others, were reviewed. They were discussed from the stand point of (1) Understanding the mechanism of the phase transformations and (2) Developing new alloy materials of high damping capacity for application to noise and vibration abatement. Pha...

A high damping capacity is considered as one of the important functional properties of shape memory alloys. Those properties are related to a thermoelastic martensitic transformation. As a consequence of this transformation, the internal friction or damping can be investigated for three different states: 1. during thermal transformation cycling, 2. during martensite induced strain cycling at co...

Abstract This paper considers a one-dimensional thermoelastic Timoshenko beam system with suspenders, general weak internal damping time varying coefficient, and time-varying delay terms. Under suitable conditions on the nonlinear terms, we prove stability result for model, where exponential polynomial decay are special cases. We also gave some examples to illustrate our theoretical finding.

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,...
