Abstract
A surface-cracked specimen has been developed that features a web whic h facilitates fatigue precracking. In addition, when the web is remove d, the remaining semi-elliptical surface crack forms a ''natural'' int ersection with the free surface. The specimen, which resembles an elon gated compact tension specimen, is quite efficient in its load require ments; relatively low loads are necessary to produce a given level of stress intensity factor.
