A REVIEW OF THE PLANE-STRESS FRACTURE MECHANICS PARAMETER KC DETERMINED USING THE CENTER-CRACKED TENSION SPECIMEN

The report discusses the current status of the center-cracked tension (CCT) specimen as a means of determining the plane-stress fracture-mechanics parameter Kc. The effect of specimen geometry (width and crack length) together with that of specimen thickness is illustrated by examples from NRL research. The experimental parameters employed at NRL are detailed together with those in use at other laboratories for the purpose of assisting in the development of a standard procedure for such testing so that data can be reliably compared.
