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 ...

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

Ultrasonic VHCF Tests on Very Large Specimens with Risk-Volume Up to 5000 mm3
Applied Sciences, 2020 The research on the size-effects in Very-High-Cycle Fatigue (VHCF) has recently drawn the attention of several scholars. The fatigue cracks in VHCF originate from the largest defect present within the loaded material volume (risk-volume) and the larger ...

Simulation of microstructural damage evolution during very high cycle fatigue (VHCF) using the boundary element method [PDF]
PAMM, 2013 AbstractA simulation model for damage evolution in slip bands under VHCF condition is presented. By use of a numerical method it is applied to a real simulated microstructure of AISI304. It considers orientations of slip systems as well as individual anisotropic elastic properties in each grain.

Crack growth behaviour of aluminium wrought alloys in the Very High Cycle Fatigue regime [PDF]
MATEC Web of Conferences, 2018 Investigations have shown that in the regime of Very High Cycle Fatigue (VHCF) “natural” crack initiation often takes place underneath the material surface leading to crack propagation without contact to atmospheric components.

Very high cycle fatigue (VHCF) response of an Additively manufactured Nitinol
International Journal of FatigueThis work investigates the Very High Cycle Fatigue (VHCF) response of an Additively Manufactured (AM) Nitinol alloy. To resemble in-service loading conditions of typical Nitinol components, an innovative experimental setup has been proposed, where the martensite/austenite transformation fraction is controlled by applying a mean static compressive load ...

VHCF Response up to 109 Cycles of SLM AlSi10Mg Specimens Built in a Vertical Direction
Applied Sciences, 2019 It is well-known that many manufacturing parameters affect the quasi-static and the fatigue response of additive manufacturing (AM) parts. In particular, due to the layer-by-layer production, the load orientation, with respect to the building direction ...
