-Curve Round-Robin Program for ASTM Recommended Practice for -Curve Determination (E 561)



A round-robin program sponsored by ASTM Task Group E24.01.02 on Crack Growth Resistance Curves was conducted to establish guidelines on variability for a Precision and Accuracy statement for ASTM Recommended Practice for R-Curve Determination (E 561). Two high strength aluminum alloys were tested by seven participants using the compact configuration specimen. The results of these tests are summarized herein, and a Precision and Accuracy section given along with variability at four levels of effective crack growth.
