Microscopic Damage Evolution During Very High Cycle Fatigue (VHCF) of Tempered Martensitic Steel
Procedia Engineering, 2016 AbstractDimensioning of high-strength steels relies on the knowledge of Wöhler-type S/N data and the assumption of a fatigue limit for applications where the number of load cycles exceeds 107. Very high cycle fatigue (VHCF) experiments applied to a 0.5C-1.25Cr-Mo tempered steel (German designation: 50CrMo4) revealed surface crack initiation at prior ...

The effect of quenching and defects size on the HCF behaviour of Boron steel [PDF]
, 2014 This work investigates the effect of natural and artificial surface defects and quenching on the fatigue strength of a Boron steel (22MnB5). A vast experimental campaign has been undertaken to study the high cycle fatigue behaviour and more specifically ...

Assessment of Very High Cycle Fatigue (VHCF) Effects in Practical Applications
Procedia Engineering, 2013 AbstractFatigue designing of high-stressed engine components is a key factor for reliable power train systems in automotive industry. In this context load assumptions are very important since this is attended with a pre-designing of important machine elements. Load analyses are done usually by experimental methods since the accuracy of load simulations
