Effects of flight load spectrum variations on fatigue life of riveted specimens and crack propagation in sheet made of Alclad 7075-T6

Riveted specimens that are considered representative for F-27 type wing structure were subjected to comparative flight simululation test in which the gust load severity and Ground-Air-Ground cycle were systematically varied. The effect of these variations on crack propagation behaviour was studied by means of crack growth tests on 2 mm sheet...
