Thanks. I would add that any structure (including airframes) has a maximum fatigue life determined by magnitude of force vs number of repetitions. Fatigue failure could happen due to even relatively low forces but requiring more repetitions. But I guess in the evolution of airframes engineers design out these problems by way of structural configuration and use of materials and wind tunnel and strain gauge tests to determine nature of forces during flight. Does anyone happen to know the percentage composition use of composite materials vs traditional aluminium in modern fast jets?
