The boundary element method (BEM) is used to develop an effective calibration method for the localized DCPD crack measurement technique. Electrical potentials are obtained from a three‐dimensional BEM analysis of a flat plate specimen containing a pair of coplanar coalescing surface cracks. This calibration technique is developed as part of a study of fatigue crack propagation and coalescence. The development of this calibration technique is presented with an evaluation based on the experimental results.
