Advanced fatigue testing methods — Part 2: Stiffness method

Scope

This CWA describes the procedure for the evaluation of the fatigue resistance of metallic alloys by means of the stiffness method. The document provides the guidelines for specimen preparation, testing and data post-processing as well as the limitations of the method.
NOTE 1 The test method outlined in this document is designed to rapidly evaluate the fatigue resistance of metallic materials. It is essential to note that the fatigue values obtained through this method are intended for material selection purposes and should not be employed for design considerations.
