The goal of this review is to examine the possible use of ex-post quantitative fractography in development of aircraft design concepts. The resent investigations using quantitative fractography for the reconstitution of fatigue process history indicated limitations of fatigue crack growth and material toughness-based tests in interpreting fatigue behaviour. Inevitable deviations in the in-service load histories, changes in mission types, increase in weight and severity of service conditions resulted in fatigue problems that could not be foreseen by the initial Safe-life and Damage-tolerant designs. However, to ensure the validity of results, there is a need for standardization and unified methodology in fractographic analysis, particularly when it comes to failure analysis.
