Abstract
"The fatigue notch size effect was investigated using the PICC-RICC model. The initial crack length (a$\rm\sb{i})$ for propagation was estimated. The predicted notch fatigue strength compared favorably with the Initiation-Propagation (I-P) Model prediction and test data. The existence of a ""worst case notch"" previously postulated using the I-P Model was confirmed."
