Abstract

This book concisely reviews the different design philosophies which have been employed in fatigue design of aircraft structures and the recent evolution of the subject. Figure 1.1 contrasts percentage of failures in general engineering components and in aircraft components, and shows that fatigue is the main source of failure in aircraft structures. Diversification of airframes, from completely metallic to the current high interest on composites and use of a variety of materials may impact the percentile distribution of failure cases, but the predominance of fatigue will certainly continue for metallic materials. Of course the figures cited correspond to a certain universe of cases; Nishida, reporting on the experience of failure analysis of mechanical components in his laboratory, mentions an even greater percentage attributable to fatigue, see Table 1.1, from Nishida (Failure analysis in engineering applications. Butterworth-Heinemann, 1992.)
