Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 5, Page 1731-1747, May 2024.Abstract Very high cycle fatigue (VHCF) experiments are limited in practice due to their long testing times. In ultrasonic fatigue test (UFT) systems, the cyclic oscillation is applied using resonance at 20 kHz with a pulse and pause sequence. However, determining optimal pulse durations to achieve minimal testing time and avoid thermal‐induced fatigue

The Effect of Microstructure on the Very High Cycle Fatigue Behavior of Ti-6Al-4V Alloy
MetalsCrack initiation plays a major role in very high cycle fatigue (VHCF) life, and the initiation of cracks is related to slip behavior. There is a need for improvement in the understanding of the influence of Ti-6Al-4V microstructures on VHCF performance ...

Procedia Structural Integrity, 2019 Abstract High-loaded tempered steels, being used in mobility, power generation and plant engineering, are frequently exposed to very high numbers of loading cycles (up to 1 billion cycles). Optimization and fatigue testing for such conditions is challenging and difficult, since damage is concentrated to very small areas of local cyclic plasticity ...

, 2022 The fatigue assessment of safety relevant components is of importance for ageing management with regard to safety and reliability of nuclear power plants. Austenitic stainless steels are often used for reactor internals due to their excellent mechanical and technological properties as well as their corrosion resistance.

Procedia Materials Science, 2014 AbstractThe exploration of fatigue mechanisms in the VHCF regime is gaining importance since many components have to withstand a very high number of loading cycles due to high frequency or long product life. In this regime, particular attention is paid to the period of fatigue crack initiation and thus the localization of plastic deformation.
