Abstract:

The purpose of the fatigue prediction program at UCLA is to characterize statistical changes taking place in the microstructure during fatigue of metallic alloys and to develop stochastic life prediction models based on these characterizations. In the three-year Phase I of the program the microstructures and fatigue behaviors of 7050 and 8090 aluminum alloys will be studied. This will be followed by the two-year Phase II during which the life prediction models developed for the aluminum alloys will be generalized to predict fatigue limits in steels and superalloys. During this stage of the program also an expert system for an easy access to all results will be developed.
