A comparison with the fatigue results led to the following conclusions : ( i ) when the longest axis of the defect is perpendicular to the loading axis , modelling the defect as an equivalent inertia prolate ellipsoid gives better results ( 5 % error on the fatigue limit ) than modelling it as a simple equivalent sphere ( 22 % error on the fatigue limit ) , ( ii ) the prolate ellipsoid is not relevant when the longest axis of the defect is oriented along the loading axis ; in this case an oblate equivalent ellipsoid should be used , ( iii ) the concept of ‘ size ’ for a complex 3D shaped defect should be linked to the inertia and the loading , ( iv ) with this approach , surface defects are shown to be more critical than internal ones for fatigue life and , ( v ) a 3D defect criticality map of the entire sample can be plotted to provide visual feedback on which defects are the most critical for fatigue life .
