Section 6.2.0. Damage Development And Progression
Fatigue-crack-growth prediction is complicated by the
assumptions that have to be made for the progression of damage through the
structure (continuing damage and remaining structure damage). These damage assumptions are specified in
JSSG-2006 Table XXX and will not be repeated here. This section will discuss interpretation of these requirements
through a series of three examples of increasing complexity. The examples pertain to a Slow Crack Growth
component, a Multiple Load Path Dependent, Fail Safe structure, and a Crack
Arrest, Fail Safe structure, in this order.
They are illustrations of the analysis procedure. No general rules can be given.
