... fatigue testing brittle fracture slip grain boundaries surface cracks optical microscopy The application of damage tolerance methods to high cycle fatigue (HCF) is hindered by the anomalous behavior of microstructurally “short” cracks that can control fatigue life. This anomalous behavior can...
