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

open access: yesFatigue & 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

open access: yesHangkong 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.
