Hi all, I've finished a hypothetical problem in which I have determined the optimum damping ratio $\zeta$ for a specific system. This [tex]$\zeta$[/tex] value (0.265 in my case) minimizes the peak force transmitted through an object. My next step is to take this [tex]$\zeta$[/tex] value and find some sort of "real-world" material or product (wood, cork, rubber, commercial-off-the-shelf damper, etc), that has a [tex]$\zeta$[/tex] value close to this so that I can basically say: "Here's the ideal [tex]$\zeta$[/tex] value, here's how close you can get to that using this material or that material". I'm not sure where I can find a list of common materials and their associated damping ratios, or if such a list even exists in the first place? Any advice? thanks in advance.
