In the high-cycle fatigue regime, it is assumed that crack initiation mechanisms and short fatigue crack propagation processes govern fatigue life of a component. Moreover, it is now becoming accepted that the conventional fatigue limit does not impl

The propagation behaviour of short cracks under cyclic loading is simulated using a mechanism-based model for two-dimensional crack propagation in stage I. Experimental investigations on a duplex steel have been performed to characterise the differen

Microstructural short fatigue cracks are known to exhibit an abnormal propagation behavior as compared to long cracks, which grow by a rate that can be described by, e.g., the Klesnil–Lukas relationship. By means of carefully recording crack length

On the basis of a thorough experimental study of the interactions between microstructural features, like the crystallographic orientation distribution and the respective crack propagation rate a numerical micro-mechanical crack-propagation model has

Cyclically loaded components in structural applications often undergo a stress amplitude which is close to the fatigue limit of the material used. Under such conditions, crack initiation and short crack propagation is considered to play an important

Up to 90% of the fatigue life of engineering alloys results from the initiation and propagation of microstructurally short cracks. Owing to their strong interactions with microstructural features, e.g. grain and phase boundaries, they exhibit substan
