OS11W0385 Gigacycle fatigue and fatigue crack growth

Abstract

Fatigue failure in the very high cycle (gigacycle) regime plays an important role in many technical fields. Appropriate testing techniques have been developed and improved in recent years. Results of investigations on different materials like high strength steels, aluminium alloys, magnesium cast alloys and titanium alloys are reviewed in the present paper. Life time as well as fatigue crack growth measurements including endurance limit and threshold crack growth behaviour are reported.
