Abstract
The damping in uniform and nonuniform cantilever beams was measured at resonance for a range of amplitudes of simultaneous steady-state first and second mode vibration. For two linear materials, aluminum and crossply fiberglas, the damping factor in each mode is independent of amplitude and unaffected by the presence of the other mode. For a fully annealed tool steel with highly nonlinear damping, the damping factor in each mode is markedly increased by the presence of the other mode.
