Abstract
This report describes experiments carried out to verify the theories of ASD Technical Report 61-467, Part I, which predicted the energy dissipation in a simple lap joint with a visco-elastic interfacial layer. The effect of the visco-elastic layer on the fatigue life of such a joint is also investigated. The complex shear modulus of the visco-elastic material used (Polyvinyl Actetate) has been measured for a range of frequencies and temperatures. This permitted an optimum joint configuration to be chosen and provided data for comparing theoretical with experimental values of the energy dissipated in the joint. Experiments on singly riveted lap joints have indicated that a considerable damping increment can be obtained by the addition of the damping layer, although the magnitude varies considerably with frequency and temperature. Fatigue tests on singly riveted lap joints have indicated that, within the limits of the investigation, the presence of the visco-elastic layer improves the fatigue life of the joint.
