Abstract:
As one of the direct applications of complex damping theory, a useful property of structural damping is presented in this paper. If a structure is linear and lightly damped, (i.e. the maximum damping ratio < 0 .. 3), then increased damping of the structure will result in proportional change in each modal damping ratio of the system. This property is particularly useful in damping re-design and damping measurement. A number of experimental and numerical exariples are also presented.
