Review of aeronatical fatigue investigations in the Netherlands during the period march 1977 - february 1979

Paper presented at the 16th ICAP Conference, Brussels, 14 and 15 May 1979.

Effect of an anti-corrosion penetrant on the fatigue life in flight-simulation tests on various riveted joints

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...

The significance of cladding for fatigue of aluminium alloys in aircraft structures

Flight-simulation tests were carried out on sheet specimens notched "by an open hole (Kt = 2.66). The material was 2024-T3 in three conditions; Alclad, bare and chemically milled. The crack initiation period and the crack propagation period were considerably shorter for the Alclad material. The significance of the cladding, both for constant...
