Abstract : This report describes experiments to measure energy dissipated under harmonic loading at a riveted joint with a visco-elastic interfacial layer. Comparison is made with theoretical results, and reasonable agreement is found. Fatigue tests on damped joints show that the damping layer increases fatigue life for given applied load levels. Description is also given of apparatus developed for measuring complex shear modulus of layer material. (Author)
