Model for Prediction of Fatigue Lives Based Upon a Pitting Corrosion Fatigue Process
SourceThe pitting corrosion fatigue process is postulated to be a possible environment/deformation synergism that might explain the initiation of Mode I cracking in materials subjected to the combined action of environment and alternating strain. A conceptual model for such a process is presented that involves utilization of an empirical pitting rate curve and a Weibull fit of the appropriate crack growth data. An experimental technique for observing the growth of pits under cyclic loading is described. Some shortcomings of the conceptual model and needs for additional research are discussed.
