The process of fatigue failure beyond 10~7 cycles for a metallic material subjected to cyclic load is called very-high-cycle fatigue(VHCF). This review will summarize the research progress of VHCF starting with its origination in early 1980s, until the cuttingedge development in recent years. After Introduction, this review contains following parts:Origination of VHCF research, Main characteristics of VHCF, Characteristic region of crack initiation and related parameters for VHCF, Formation mechanisms and m...
