Abstract	The damping of free-free beams vibrating in dense, still fluids has been studied experimentally. The decay of transverse vibration following an impulse load on the beams was dominated by viscous damping at low frequencies, both of which were measured on beams of various geometries. The results raise considerable question concerning the validity of measuring the damping characteristics of material samples in water. It appears that the material samples must be designed to minimize spurious fluid-damping effects, otherwise the results may be more particular to the experiment configuration than to the material itself.
