Method for Determining Fatigue Limit Taking Into Account the Effect of a Surface Layer

Аннотация

A method is proposed for determining the fatigue limit of metallic material components based on measuring hardness, production residual stresses, surface roughness, and some other parameters. A dependence is given for fatigue limit on surface layer quality parameters. Application of the method is demonstrated on the example of steels 30KhGSNA, U8, titanium alloy VT3-1, and aluminum alloy D16 after different treatment.
