Fatigue Crack Growth History in Damage Tolerance Design of Aircraft Structures
Original language description
Knowing the real history of the fatigue process is a valuable asset to for design, development, and reliable operation of structures exposed to time-variable loading service conditions. Information of this type is encoded in the fracture morphology. Thisinformation can be decoded by quantitative fractography and transformed it into a form interesting from the engineering point of view. Application of these fractographic methods is conditioned by the existence and detectability of fractographic featurescorrelated with fatigue crack growth rate. In the paper presented, three various fractographic features are used for fractographic reconstitution - striations (constant amplitude loading), beach marks (simple program loading), and special inserted fracture marks (complex program loading). The importance and irreplaceable role of the fractographic analysis is illustrated by some case studies dealing with full-scale fatigue tests of aircraft structure parts.
