Abstract

The Aeronautical Research Laboratories have been engaged in full scale aircraft structural strength testing for over 20 years, during which period extensive investigations have been conducted into the fatigue behaviour of aluminium alloy riveted structures.
Two testing procedures have been employed, namely, the hydraulic loading method and a development of the resonant vibration technique. A recent development of the hydraulic rig has enabled the application of a prescribed random sequence of 24 load levels representative of service loading.
The comprehensive experimental investigation has enabled the following aspects of fatigue behaviour to be examined:
(i) The nature of the fatigue failure of a complex structure;
(ii) Comparison with data on similar structures and notched material leading to a representative fatigue diagram for this type of construction;
(iii) The statistical aspects of fatigue life variation;
(iv) The effect of preloading on the fatigue strength;
(v) Crack propagation and the residual strength of the cracked structure;
(vi) Theories relating to the fatigue damage accumulation under a complex loading sequence.
Possible future fatigue tests representative of supersonic aircraft service loadings are discussed.
