Book Description
A theoretical analysis has been made of the inaccuracies involved in the representation of a continuous distribution of aircraft gust loads by a program of loads at a few discrete levels to be applied to a fatigue test specimen. These inaccuracies arise through the failure of the simplified test load program to inflict fatigue damage at the correct rate in those parts of the specimen where the stress per unit acceleration has a value other than that for which the test loading was derived. Three severities of gust spectrum and two families of S-N curve were used in the fatigue damage calculations which were based on Miner's hypothesis. The number of discrete load levels in the derived programs varied from one to seven. (Modified author abstract).
