An Analytical Model Which Combines Roughness- and Plasticity- Induced Fatigue Crack Closure
"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 …
