Summary:This attempt proposes an engineering design approach to predict the high-cycle fatigue limit of shot-peened parts. The effects of the shot peening surface treatment on the high-cycle fatigue performance of Waspaloy, a nickel superalloy widely used in the airframe sector, are investigated. The proposed approach consists in (i) predicting the initial shot peening surface properties, (ii) simulating the evolution of the shot peening surface properties occurring during fatigue loading, and (iii) deducing the new fatigue limit of the shot-peened surface in the case of tensile, torsion, and combined tensile-torsion loading. The physical model is implemented and analyzed using the finite element analysis. The mathematical model sheds light on the evolution of the shot-peened surface performance. It allows determining the influence of the industrial parameters in order to optimize the shot peening process operating conditions. The prediction of the fatigue performance for different shot peening conditions leads to have physically consistent results.
