An analysis of the damping of a cantilever beam by an added configuration involving viscoelastic interfaces is presented. The damping is obtained after first calculating the response of the system to low frequency cycling under constant sinusoidal force amplitude. Calculations are made for optimum values of damping due to viscoelastic interfaces. These optimum values are compared with calculated values of damping due to hysteresis of the structural material of a plain cantilever beam.nResults of an experimental check of the configurational damping theory are presented. The experimental data show fair agreement with the predicted values both as to order of magnitude and trends toward optimum values. The limitations of the theory and reasons for discrepancies between theory and experiment are discussed. Possible extensions and refinements of the theory are also discussed.
