Rayleigh expression

WebRayleigh damping (eqn (1)) produces a total curve that can accurately match modal damping values at one or two natural frequency points. Consequently, if a structure has one or two dominant frequencies, Rayleigh damping is precisely able to approximate the dynamic behaviour of the structure. WebSep 7, 2024 · The negative sign here reveals that the number of modes decreases with increasing wavelength. Now to get the number of modes per unit volume per unit wavelength, we can simply divide by the volume of …
