Proposal of a new subsurface-to-surface flaw transformation rule for fatigue crack growth analyses

Lacroix, V.*; Bouydo, A.*; Katsumata, Genshichiro*; Li, Y. ; Hasegawa, Kunio

This paper summarizes the steps leading to the improvement of the ASME Code Section XI subsurface-to-surface proximity rule. Based on fatigue crack growth calculations and refined investigations, the paper proposes a new limit value for the surface proximity factor. As a result, a proposal for modification of the ASME Code Section XI, Appendix C is provided. The paper is used for the technical basis of this proposal.
