Identification of Test Structures for Reduced Order Modeling of the Squeeze Film Damping in Mems
In this study the dynamic behaviour of perforated microplates oscillating
under the effect of squeeze film damping is analyzed. A numerical approach is
adopted to predict the effects of damping and stiffness transferred from the
surrounding ambient air to oscillating structures ; the effect of hole's cross
section and plate's extension is observed. Results obtained by F.E.M. models
are compared with experimental measurements performed by an optical
interferometric microscope.Comment: Submitted on behalf of EDA Publishing Association

Scaling Laws for Spreading of a Liquid Under Pressure
We study squeeze flow of two different fluids (castor oil and ethylene
glycol) between a pair of glass plates and a pair of perspex plates, under an
applied load. The film thickness is found to vary with time as a power-law,
where the exponent increases with load. After a certain time interval the area
of fluid-solid contact saturates to a constant value. This saturation area,
increases with load at different rates for different fluid-solid combinations.Comment: 10 pages, 5 figure
