Abstract : An experimental procedure for the measurement of material damping is described. In this procedure, the free decay of free-free beams, when lofted into free fall in a vacuum, is recorded and analyzed. Tests were performed on aluminum, graphite/epoxy, and graphite/magnesium metal matrix materials.
