In this paper, residual stresses fields generated by plastic preload in tension using finite element method. Von Mises criterion was applied for isotropic hardening in behavior law of 7075 Al-alloy. Finite plate with central hole in 7075 Al-alloy was used for this investigation study. Compressive residuals stress at notch was generated after unloading. Results shown those fatigue life and fatigue crack growth rate (FCGR) were affected by residuals stresses fields.
