Hi guys, working a project where I need to guess the damping ratio (used for a numerical analysis) based on other properties of a material. We're looking to use an RTV as a vibration damper (we don't need a lot) but I can't seem to get any vibrational properties (called Honeywell, Dupond, GESilicones, etc). Hell, if anyone has damping ratios for 'any' RTV, it would help a lot. If anyone even has a list of any different elastomers with damping ratios, it would help a lot. edit: Directly related is a properties called [tex]\tan\delta[/tex] which I could use as well. Either work.
