The influential factors on very high cycle fatigue testing results
MATEC Web of Conferences, 2018 When the fatigue cycle is extended from high cycle (105~107) to very high cycle (107~109), the fatigue testing results will be more sensitive to the influential factors such as specimen size, specimen surface roughness and the inclusion size.

Assessment of Fatigue Life and Failure Criteria in Ultrasonic Testing Through Thermal Analyses
Applied SciencesAn experimental study was conducted to analyze temperature evolution during very high cycle fatigue tests. The temperature–number of cycles (T–N) curve is typically divided into three phases: Phase I—a rapid temperature increases at the start of the test,

Crack path for run-out specimens in fatigue tests: is it belonging to high- or very-high-cycle fatigue regime? [PDF]
Fracture and Structural Integrity, 2015 Fatigue tests run-out specimens up to 106 – 5x107 load cycles are used to determine the stress level named “fatigue limit”. Nevertheless, it is not clear what kind of fatigue cracking takes or will take place in these specimens. To discuss this problem,

Very High Cycle Fatigue (VHCF) of notched specimens: a review
Fracture and Structural IntegrityA large number of mechanical components are subjected to fatigue loading beyond 106 cycles. The VHCF behaviour of smooth specimens has been extensively investigated in the recent years, even if more efforts are necessary to reveal the mecahnism ...
