Schijve, J. Institution National Aerospace laboratory NLR Date 1969-12-31 Abstract Six types of riveted specimens including lap joints and single and deuble strap joints have been compared both, in constant-load-amplitude tests and in programme tests. In the programee tests, based on a gust load spectrum, the endurance of the double strap joint specimens was about three times as long: as that of the single lap joint and the single strap joint with low secondary bending stresses, and it was about ten times as long as the endurances of the joints with severe secondary bending stresses. The fatigue strength for N - 10 7 load cycles decreased by severe secondary bending in the specimens to about half the strength of the double strap joints. The relation between the calculated bending stresses and the fatigue strength was analysed with respect to design aspects.
