Abstract
Different approaches for establishing Shear Fracture Appearance (SFA) on tested Charpy specimens were assessed and compared, namely (in order of increasing expected accuracy): estimates based on characteristic forces from instrumented Charpy tests, optical measurements using image analysis software, and measurements performed with the aid of a Scanning Electron Microscope. Comparisons between different SFA values for 129 instrumented Charpy tests currently included in the NIST database allowed us to establish the relationships between the different available approaches and formulate recommendations for the revision of the ASTM E2298 and ISO 14556 standards, which currently provide four empirical correlations that can be used to estimate SFA.Citation
