complex damping


complex damping
damping in which the force opposing the vibratory motion is variable, but not proportional, to the velocity. In the field of aircraft flutter and vibration, complex damping is also used to denote a specific type of damping in which the damping force is assumed to be harmonic and in phase with the velocity but to have an amplitude proportional to the amplitude of displacement.
