Calibration equation for evaluating crack depth based on the d.c. potential drop technique with the use of extremely adjacent probes is derived, where the path-independent integral jc for electric crack problems is utilized. Some experiments for laboratory specimens validate the use of the equation for nondestructive evaluation of cracks based on the utilization of a small sensor composed of the probes.
