| Abstract | The combined effects of corrosion and cyclic loading have been shown to produce cracks from corrosion pits and pits have frequently been the source of cracks on components operating in fleets of aircraft. Once the pit, or group of pits form, the rate of pit growth is dependent mainly on the material, environmental conditions, temperature, and type and state of stress. Therefore, to estimate the total corrosion fatigue life of a component, it is of great importance to develop realistic models to establish the component life in these situations and to formulate methods by which designers and operators know likely sources of pitting early in the design and fleet operation. In this manner the structurally significant items can be classed by susceptibility to pitting corrosion fatigue as well as conventional fatigue criteria. Therefore, to understand this phenomenon, some models based on Pitting Corrosion Fatigue (PCF) mechanisms and understanding have been proposed in the past and new ones are emerging. |
