Abstract:
By defining fatigue failure as an ultimate load failure of a structure damaged in fatigue by operational loads, the estimate of fatigue life can be reduced to that of a mean return period of an ultimate load type of failure for which statistical methods of safety analysis have already been developed. By applying such methods in conjunction with a simple fatigue damage function the fatigue sensitivity of a structure can be evaluated in terms of the ratio of the return periods of fatigue failure and ultimate load failure, as suggested in WADD Technical Report 61-53, July 1961.
