— This paper presents a review of the application of LEFM to the characterisation of fatigue crack growth. This part covers national standards and other documents of comparable status that (a) offer explicit advice on the use of fatigue crack growth data, and (b) in which crack growth considerations are implicit. Documents falling into the first category were noted to have many features in common, differences occurring only in areas where the current understanding of the subject is far from complete (e.g. variable amplitude loading, long life, etc.). Documents implicitly addressing fatigue crack growth comprise three distinct groups: (i) those which aim to simplify fracture mechanics analyses for the user, (ii) those in which fracture mechanics has influenced design criteria, and (iii) those which aim to provide inspection and/or acceptance criteria. As with the “explicit documents”, a degree of commonality was observed within each group of “implicit documents”, the exception being the military aircraft specifications of the U.K. and the U.S.A.
