The Behaviour of Short Fatigue Cracks
The Behaviour of Short Fatigue Cracks (EGF Publication No. 1) is a specialized collection of research papers focused on the critical and often anomalous growth patterns of small-scale fatigue cracks in engineering materials. This volume addresses a significant gap in traditional fracture mechanics: the tendency of "short" cracks—typically less than one millimeter in length—to propagate at rates significantly higher than those predicted by long-crack data at equivalent stress intensity factors.
The text explores the complex interplay between material microstructure, local plastic deformation, and environmental factors that drive crack initiation and early growth. It provides detailed analysis of the "threshold" problem, where short cracks often grow below the nominal fatigue limit of the material. By consolidating multi-disciplinary studies on metallurgy, stress analysis, and structural integrity, this book serves as a vital reference for researchers and engineers aiming to improve the predictive accuracy of fatigue life models and ensure the safety of components subjected to cyclic loading.
