Aerospace series - Test methods for metallic materials - Determination of fatigue crack growth rates using corner-cracked (CC) test pieces; German and English version prEN 3873:2025
Abstract
This document specifies the requirements for determining fatigue crack growth rates using corner-crack (CC) test pieces. Crack development is measured using a potential-drop system, and the calculated crack depths can be corrected via marker bands created on the fracture surface during the test. Results are expressed in terms of the crack-tip stress-intensity range (ΔK), with crack depths and test stress level noted.
