A Model for Thermoelastic Damping in Microplates

Nayfeh A.H., Younis M.I., Virginia Tech, US

We present a model and analytical expressions for the quality factors of microplates due to thermoelastic damping. We solve the heat equation for the thermal current across the thickness of a microplate, and hence decouple [...]

Microplate Modeling under Coupled Structural-Fluidic-Electrostatic Forces

Younis M.I., Nayfeh A.H., Virginia Tech, US

We present a model for the dynamic behavior of microplates under the coupled effects of squeeze-film damping, electrostatic actuation, and mechanical forces. The model simulates the dynamics of microplates and predicts their quality factors under [...]
