Stress corrosion cracking is recently observed in the heat affected zone of welded joint of the core shroud of boiling water reactors. Stress intensity factor is essential for evaluation of crack growth behavior in stress corrosion cracking. In this study, stress intensity factor of surface crack under residual stress field was calculated using two experienced equations in API RP579 with the aids of finite element method. The feasibility and reliability of the used methods were discussed.
