Voltage response in piezoelectric patch for Configuration 1
Figure 25.3(a) shows the voltage response in the elements when delamination is considered in element 1. A drop in voltage from 0.31V to 0.30V is predicted. Since element 1 is not receiving any load, a localized stress redistribution will cause modified voltage responses in elements located close to it.

Figures 25.3(b) to 25.3 (f) show the voltage responses when delaminations are assumed in elements 2, 3, 4, 5 and 8 respectively. Elements 2 and 3 (and their corresponding symmetric pairs 7 and 6) show little change in response due to delamination [Figures 25.3(b) and (c)].
