Subject: REVISION: Eigenfrequency Analysis of Single Stack Complete 

My previous eigenfrequency analysis was incorrect by two orders of magnitude due to the misuse of Young's Modulus information for Viton. After editing this parameter (as documented on 7/14 19:00), the eigenmodes became much more reasonable. I also discovered the Deformation option under the Surface Plotting Options, which makes the eigenmodes of the single stack much more apparant.

Attached are pictures of the first four eigenmodes:

First Eigenmode: y-translational, 7.49 Hz

Second Eigenmode: x-translational, 7.55 Hz

Third Eigenmode: z-rotational, 8.63 Hz

Fourth Eigenmode: z-translational, 18.26 Hz
