DEVELOPMENT OF METHODOLOGY FOR PREDICTING FATIGUE LIFE OF FIBER REINFORCED METAL LAMINATES

The paper presents a review of the characteristics of a new group of aircraft materials,the fiber reinforced metal laminates (FRMLs), the mechanism of fatigue damage, and the industrial application. Several important issues, including the bridging stress, the delamination growth and the prediction of the fatigue crack growth rates and the fatigue life, were addressed and summarized. Some suggestions on the prediction of fatigue life were proposed.
