N2 - The effects of blade-to-blade variations in the damping coefficients on the forced response of a bladed disk are investigated. It is found that this nonuniformity of the disk can lead to variations in the blades' amplitudes of response which are similar, in magnitude, to those obtained with stiffness mistuning but are potentially more dangerous because of the skewness of the distribution toward large amplitudes. The influence of various structural parameters on the scatter of blade amplitudes is also studied. Finally, the adequacy of the combined Closed Form - Perturbation (CFP) method is demonstrated by comparison with simulation results.
