A COMPARISON BETWEEN SAFE LIFE, DAMAGE TOLERANCE AND PROBABILISTIC APPROACHES TO AIRCRAFT STRUCTURE FATIGUE DESIGN

Roberta Lazzeri

Abstract


The different fatigue design approaches for typical aeronautical structures are compared: a computer code has been used in order to investigate the different approaches such as Safe Life, Damage Tolerance and probabilistic approaches to analyze two fundamental aspects: risk of failure and costs. The acceptable maximum risk level has been established and thresholds and inspection intervals have been found to ensure operating life without catastrophic failures.
