SONIC FATIGUE DAMPING SYSTEM DEVELOPMENT

Abstract

A litrature search was made to survey commercially available damping and adhesive materials and to determine the physical properties of those materials which reduce resonant-stres . Damping ratis of 108 uncoated strip specimens have been meaured and recorded. A load-stress curve has been plotted for 30 uncoatedl-ner adhesion test specimens. Thirty viscoelastic materials have been acquired. Coupons of these mials have been prepared for peel strength and environmental tests. Investigation of the high-temperature strain gauge techniques required for the program has been initiated. (Author)
