“…Paris et al revealed that crack propagation only occupies a tiny portion of total life in the VHCF regime whereas the crack initiation is of primary importance . Furthermore, several fatigue experiments are performed to evaluate the number of cycles for crack propagation from an interior inclusion under VHCF . Nakasone et al simulated the internal crack propagation using the well‐known Paris law and found that crack propagation life is approximately 10 2 to 10 5 cycles of the total life, and can be negligible compared with the longer crack initiation life.…”

“…Nakasone et al simulated the internal crack propagation using the well‐known Paris law and found that crack propagation life is approximately 10 2 to 10 5 cycles of the total life, and can be negligible compared with the longer crack initiation life. Furthermore, by using a thermo‐mechanical approach, Wagner et al reported that more than 90% of the total fatigue life in the VHCF domain is consumed in the crack initiation stage within the FGA . Although some experiments or measurements have revealed the importance of crack initiation in the VHCF process, it is still a difficult task to establish a reasonable VHCF life model to evaluate the number of cycles leading to initiation.…”

The understanding of very high cycle fatigue (VHCF) mechanisms is critical to the development of life prediction approach. For this purpose, high cycle fatigue (HCF) and VHCF properties of a surface‐treated 17Cr‐Ni steel were investigated under axial loading with stress ratio of 0. This steel exhibits the constantly decreasing S‐N characteristics associated with the inclusion‐fisheye induced failure under the HCF and the inclusion‐FGA (fine granular area)‐fisheye induced failure under the VHCF. The cyclic pressing plays an important role in the FGA formation process, but the FGA still can be observed for the stress ratio of zero due to the slight crack closure effect. Two life modelling approaches associated with related failure mechanisms in the HCF and VHCF regimes are proposed based on the agreement between experimental and predicted results.

“…Furthermore, combined with the analysis of energy dispersive X-ray spectrometer (EDS), some non-metallic inclusions of Al 2 O 3 are found in the steel matrix in Figure 2 . Based on the reference [ 22 ], the elastic modulus and Poisson's ratio of inclusion, E i and υ i are around 390 GPa and 0.25, respectively.…”

The unexpected failures of structural materials in very high cycle fatigue (VHCF) regime have been a critical issue in modern engineering design. In this study, the VHCF property of a Cr-Ni-W gear steel was experimentally investigated under axial loading with the stress ratio of R = −1, and a life prediction model associated with crack initiation and growth behaviors was proposed. Results show that the Cr-Ni-W gear steel exhibits the constantly decreasing S-N property without traditional fatigue limit, and the fatigue strength corresponding to 109 cycles is around 485 MPa. The inclusion-fine granular area (FGA)-fisheye induced failure becomes the main failure mechanism in the VHCF regime, and the local stress around the inclusion play a key role. By using the finite element analysis of representative volume element, the local stress tends to increase with the increase of elastic modulus difference between inclusion and matrix. The predicted crack initiation life occupies the majority of total fatigue life, while the predicted crack growth life is only accounts for a tiny fraction. In view of the good agreement between the predicted and experimental results, the proposed VHCF life prediction model involving crack initiation and growth can be acceptable for inclusion-FGA-fisheye induced failure.

In this study, the fatigue failure behaviors of carburized 12Cr2Ni alloy steel were examined in the long-life regime between 10 4 and 10 8 cycles with about 100 Hz under R = 0. Results showed that this alloy steel exhibited the double S-N characteristics with surface failure and interior failure. From a statistical point of view, the correlation coefficient further proved that the fine granular area (FGA) governed the fatigue performance of carburized 12Cr2Ni alloy steel. Based on the generalized extreme values (GEV) distribution and test data, the predicted maximum defect size was about 23.4 µm. Considering the effect of tensile limit, material hardness, and crack size characteristics, the fatigue strength prediction model under stress ratio of 0 could be established. The predicted fatigue limit for carburized 12Cr2Ni alloy steel at 10 8 cycles under R = 0 was 507.86 MPa, and the prediction error of fatigue limit was within 0.04. Therefore, the results were extremely accurate.
