.... Keywords: Crack, EDM, Pipeline, Fatigue, Fracture Mechanics, Notches. 1. INTRODUCTION Pipeline crack management has become a major focus for many gas and liquid transmission pipeline operators. As described by API RP 1176 (Reference 1), determination of the most appropriate method for assessing cracks...

.... This phenomenon has been attributed to the “constraint effect” on fracture. Modern constraint-sensitive fracture mechanics has brought about fundamental theoretical understandings on the constraint effects. The constraint-sensitive fracture mechanics has moved from academic circles to practical application...

... the determined crack growth rate and fracture mechanics based approach. In addition, the susceptibility of SCC was studied in detail using a decision tree approach for data mining. Some important correlations between SCC susceptibility and environmental and mechanical variables were identified and presented...
