Abstract
The SNKf concept is a method of selecting unique stress-endurance diagrams to describe the fatigue performance of aluminum aircraft structural elements. The SN curves are defined by the fatigue severity index (Kf). The shape and location of previously established control curves are modified by interpolation based on constant life diagrams to match each analysis or test requirement.
