Schijve, J. (author), Jacobs, F.A. (author)Fatigue tests were carried out on Redux and FM 123/5 bonded specimens at various stress levels, temperatures (RT to 65 C) and low and high test frequencies. Observations were made on the type of failure (bond line failure or sheet failure) and the significance of the adhesive squeezeout for crack nucleation. An analysis of the data and a...report 1984

Schijve, J. (author), Jacobs, F.A. (author)Several simple crack stopping methods were evaluated In fatigue crack propagation tests on 2024-T3 Alclad sheet specimens. After precracklng until a crack of 40 mm was obtained crack stoppers were Installed and the fatigue test was continued. Crack stoppers Installed In stop holes were: a blind rivet, a hard driven rivet, a heavily tightened...report 1984

Schijve, J. (author), Jacobs, F.A. (author), Tromp, P.J. (author)Comparative flight-simulation tests on four types of joints of 2024- T3 sheet material were carried out with and without application of the penetrant LPS-3. Types of joints were douhle strap joint with hi-lok bolts, asymmetric strap joint, lap joint with countersunk rivets and lap joint with dimpled holes. Observations on slip during the fatigue...report 1977

Schijve, J. (author), Jacobs, F.A. (author), Tromp, P.J. (author)Flight-simulation tests based on a standardized gust load spectrum were carried out in normal air, very dry air and salt water. Specimen thicknesses were t = 2 mm and t = 10 mm, mean stress in flight was 70 or 55 MN/m². In all cases a significant effect of the environment was found. Fatigue lives for t = 10 ram were much shorter than for t = 2...report 1976
