Abstract
The objective was to initiate a program for generating relevant airframe material fatigue data base required for engineering support of the Canadian Air force Fleet operating in the Atlantic region. This study has identified representative environmental conditions and defined a corrosion and fatigue testing procedure. It was followed by testing specimens of 2024-T3 clad aluminum sheet each containing a drilled central hole. The specimens were subjected to varying durations of pre-exposure to salt spray under controlled laboratory conditions and then fatigue tested with constant amplitude cyclic loading. The data gathered was used to generate fatigue S-N curves. The effect of corrosion pre-exposure time on fatigue life is presented.
