Research on Fatigue Notch Factor of Aluminum Corrosion Pits

Abstract:

In the midst of highly corrosive marine environment the corrosion damage is very critical in the aircraft structure. Corrosion will reduce the fatigue strength and fatigue life of aircraft structure. The fatigue notch factor is a very important factor, and which directly affects the accuracy of the fatigue life estimation result. The LY12CZ aluminum alloy of aircraft structure was accelerated tested according to equivalent accelerated corrosion testing spectrum based on key environment data, then made a fatigue test. According to the fatigue test data fatigue notch factor was calculated and then the variation law of fatigue notch factor with the corrosion life was studied.
