Microstructural and Very High Cycle Fatigue (VHCF) Behavior of Ti6Al4V-A Comparative Study. [PDF]

Materials (Basel), 2020
In this study, an investigation is carried out to evaluate and compare the material and physical properties of Grade 5 Titanium alloy (Ti6Al4V G5) samples of three different impeller manufacturers. The study aims to identify the efficient impeller core material from different Ti6Al4V G5 manufacturers.

Very High Cycle Fatigue (VHCF) Characteristics of Carbon Fiber Reinforced Plastics (CFRP) under Ultrasonic Loading. [PDF]

Materials (Basel), 2020
A liquid nitrogen cooling system was developed to ensure the successful ultrasonic testing of composite materials to characterize the very High Cycle Fatigue (VHCF) of carbon fiber reinforced plastics (CFRP). The fatigue failure of CFRP occurs even in the very high cycle range and there is no traditional fatigue limit.

Very High Cycle Fatigue (VHCF) of notched specimens: a review

Fracture and Structural Integrity
A 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 ...

Scaling of damage mechanism for additively manufactured alloys at very high cycle fatigue [PDF]

Scientific Reports
A comparative analysis of fracture mechanisms in high- and very high- cycle fatigue (HCF, VHCF) regimes was carried out based on the results of multifractal analysis of the fracture surfaces of additively manufactured 316L stainless steel samples.

Very high cycle fatigue (VHCF) response of additively manufactured materials: A review [PDF]

Fatigue & Fracture of Engineering Materials & Structures, 2021
AbstractRecently, the diffusion of components produced through additive manufacturing (AM) processes has significantly increased. Concurrently, to ensure the safe employment of AM components, the research has focused on the assessment of their fatigue response. In the present paper, a comprehensive literature review on the very high cycle fatigue (VHCF)

A review of the research on the VHCF test technology for aero-engine typical materials

Hangkong gongcheng jinzhan, 2023
As the most critical and core part of the aircraft, the aero-engine has been serving in extreme environ-ment such as high temperature and high load for a long time. Fatigue failure is one of the main causes of engine structure failure.
