WebA complication with the Rayleigh damping model is to obtain good values for the damping parameters α dM and β dK. A more physical damping measure is the damping ratio, the ratio between actual and critical damping, often expressed as a percentage of the critical damping. Commonly used values of the damping ratio can be found in the literature.
