where can I find data about the natural vibration of differrent materials ?

I would suggest looking up "normal modes of materials" on google or of whatever specific material you wnated to know about. Mainly the normal modes of a material are essentially the same and depend on the density and the speed of sound within the material if it is of course an acoustic vibration.
