Article Preview

In this paper, a linear model of thermoelastic damping in annular microplate is considered for calculating the quality factor of this damping. In this model clamped boundary condition is applied in inner and outer circular edges. In the results, there are critical radius and thickness which are calculated analytically and in these dimensions, the thermoelastic damping becomes maximal. The critical radius and thickness depend on material properties, vibration modes and frequencies, dimensions of microplate.
