About the fatigue crack propagation threshold of metals as a design criterion – A review
Uwe Zerbst,Michael Vormwald,Reinhard Pippan,Hans-Peter Gänser,Christine Sarrazin-Baudoux,Mauro Madia +5 more
TL;DR: The fatigue crack propagation threshold ΔKth is of paramount importance for any kind of damage tolerant design, but in contrast to this importance, the determination and application of the parameter is not on the firm ground as previously assumed.

Factors influencing the mechanism of superlong fatigue failure in steels
Y Murakam,T Nomoto,T Ueda +2 more
TL;DR: In this article, a particular fatigue fracture morphology in the vicinity of the fracture origin (non-metallic inclusions) of a heat-treated alloy steel, SCM435, was tested to N ≥ 10 8.

Subsurface crack initiation and propagation mechanism in high-strength steel in a very high cycle fatigue regime
TL;DR: In this article, the mechanism for the formation of the GBF area was proposed as the "dispersive decohesion of spherical carbide" model, in which during the fatigue process multiple microcracks are initiated dispersively by de-cohesion of the carbide from the matrix around a non-metallic inclusion.
