ESDU Fatigue - Endurance Data Series

Methods and data are given for strength calculations primarily on aircraft and aerospace structures. The data are principally for use when the design philosophy is one of "safe-life design", that is, the structure or component is required to be crack-free for the specified design life.

The major part of the data consists of constant amplitude stress-endurance curves (S-N curves) for aircraft materials (aluminium and titanium alloys and steels) and structural joints (riveted, bolted or bonded). In addition, a large collection of stress concentration factors is included and the principles for designing against metal fatigue are explained and illustrated with worked examples. The necessary statistical methods of dealing with small samples in design are also included, and correlated data on loading, resulting from encountering gusts and from taxiing and ground operations, are given.
