    Abstract

    In using the direct current potential drop method for crack growth measurement, a suitable reference location on the test piece of a compact tension (CT) specimen seems difficult to find and yet is highly desirable for high-temperature long-term testing. This short report presents a possible solution that seems promising based on our preliminary test results. Vanations in the potential and current lead placement were also evaluated for some typical lead configurations in CT specimens.
