Schijve, J. (author), Broek, D. (author), de Rijk, P. (author), Nederveen, A. (author), Sevenhuysen, P.J. (author)Fatigue tests were carried out on full-scale tension skins of a wing center section of 7075-T6 material. Variable-amplitude tests were carried out with the following load sequences: (a) random load, (b) program load, (c) random load with GTAC (ground-to-air cycles) and (d) program load with GTAC. Constant-amplitude tests were carried out with...report 1965

Schijve, J. (author), Nederveen, A. (author), Jacobs, F.A. (author)The size effect on crack propagation was studied with sheet specimens of 2024-T3 Alclad. Values of the width were 80, 160, 300 and 600 mm, sheet thickness 3 mm, mean stress 8 kg/mm2 and stress amplitudes 2.5, 4 and 6.5 kg/mm2. Results are compared with the theory of the stress intensity factor and the Weibull theory. Practical implications of...report 1965

Broek, D. (author), Schijve, J. (author), Nederveen, A. (author)The effect was studied of artificial aging (up to and beyond maximum hardness, both with and without prior solution heat treatment) on the crack propagation in 2024-T3 alclad sheet. All heat treatments caused a noticeable increase of the rate of crack propagation, which was correlated with a decrease of ductility. The correlation is discussed...report 1963
