Evaluation of Fatigue Crack-Growth-Rate Determination Using a Crack-Opening Displacement Technique for Crack-Length Measurement.
Abstract
Evaluation of a crack-opening-displacement (COD) technique for measurement of crack length in compact tension (CT) specimens for the determination of fatigue crack growth rate (FCGR) has proved it to be successful. Comparisons of COD-determined FCGR data with previously established trend lines for two high-strength steels are presented together with data from aluminum alloy 2024-T351.
