Small Crack Growth and Its Influence in Near Alpha-Titanium Alloys

Abstract

Small fatigue cracks are known to propagate at rates much greater than large cracks in the same material at an equivalent crack driving force. The review clarifies the small crack problem and the reasons for its existence. Some recent models, incorporating large scale plasticity, crack closure and microstructural dissimilitude, are introduced. Small crack behaviour in near alphatitanium alloys is examined.
