Soboyejo, R. Reed, J. Knott] This paper treats the calibration of the direct-current, potential difference (d.c.p.d.) technique for the measurement of the lengths of semi-elliptical ("thumbnail”) cracks. Calibrations utilised the beachmarking of steel specimens and a three-dimensional analogue method, which employed an electrolytic tank to simulate a testpiece. The agreement between the two sets of calibrations was good, and the results have been compared with an analytical solution for a semi-circular crack in a half-space.
