Abstract
Finite element procedures are used to optimize the efficiency of the electrical potential technique for monitoring the initiation and slow growth of cracks as applied to the compact tension fracture test piece. An analysis of various configurations of current input and potential measurement lead placement is performed to optimize the accuracy, sensitivity, and reproducibility of measurement and to maximize output voltages. Numerical calibration curves are computed for selected configurations and are confirmed by experimental measurements.
