WebA common method of modeling damping is Rayleigh damping, where two damping coefficients are specified. This type of damping is not directly related to any physical process, but must be seen as a way to take the total damping of a structure into account. Rayleigh damping introduces damping in a form based on Equation 2-20. songs about reuniting with an old flame https://smidivision.com
