Abstract

Systems and methods for testing and validating fatigue life of a complex structure (200) includes determining flight loads acting on the complex structure (200), identifying fatigue sensitive points (803) in the complex structure (200) in response to the flight loads acting on the complex structure (200), grouping (802) the fatigue sensitive points into a plurality of families, selecting (803) at least one representative fatigue sensitive point from each family, creating (804) at least one detail specimen that replicates the representative fatigue sensitive point from each family, fatigue testing (804) the detail specimens, and comparing (805) results determined in response to fatigue testing (804) the detail specimens to the determined flight loads. By fatigue testing (804) representative detail specimens that replicate similar or include worse geometry for fatigue life than the fatigue sensitive points in the complex structure (200), all fatigue sensitive points in the complex structure (200) are validated for fatigue life without fatigue testing every fatigue sensitive point in the complex structure (200).
