The text discusses factors that affect fatigue and corrosion behavior of welded structures and describes the application of fuzzy sets to the treatment of uncertainties associated with such behaviors. Weldment factors such as joint details and residual stresses are reviewed and environmental factors, including the randomness of the loading sequence and loading rate, are considered. Design rules which incorporate the effects of weldment and environmental factors are noted, and uncertainties which must be considered relative to the fatigue phenomenon are highlighted. These include quality control, load history, and effects of residual stresses. Corrosion factors, all of which are a function of time, are explored, and the interaction of corrosion and fatigue are analyzed. Finally, the fuzzy set theory is discussed as a way of systematically considering uncertainties of the fatigue strength of a welded steel in a corrosive environment.
