The corrosion-fatigue life of drill-pipe steels in simulated offshore-drilling environments was predicted using an analytical model. This model, named the Active-Path-Dissolution (APD) model, simulates a sequence of three ...

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 ...

Newman's Dugdale strip-yield model for crack closure was modified to estimate the crack-closure behavior of cracks emanating from notches. The results obtained using this crack-tip plastic deformation model showed that the ...

The objective of this project was to examine the fatigue behavior of thermite-welded railroad rail and in particular the occurrence of fatigue defects in the rail head. A rail-head local-stress fatigue model (RAHELS) was ...
