Abstract

Fatigue behavior of 5456-H117 aluminum alloy has been studied by fracture mechanics and conventional test methods in air and saltwater environments. The results show that fatigue resistance of the alloy is reduced greatly by the presence of saltwater at low stress or stress intensity levels. Test data of smooth and precracked specimens are combined and discussed with regard to failure predictions.
