Abstract
We present an analysis of thermoelastic damping in materials arising from the temperature dependence of the elastic moduli. We show that this form of damping can cancel thermoelastic damping arising from thermal expansion for a suitably chosen operating stress. For the case of the suspension fibers used in the gravitational wave detectors, this loss mechanism can be the dominant one.
