Fig. 9. Sensitivity of the DCPD calibration curves (dΔV PD /da) evaluated in all FE models as a function of PD probes position and for two different crack sizes: a) remote current input, Y I = ∞ , b) local current input, Y I = 11.5 mm and θ I = 0°, c) local current input, Y I = 4 mm and θ I = 0°, d) local current input, Y I = 11.5 mm and θ I = 50°. Black zones in the graphs correspond to the location of the current probe.
