Voltage response in piezoelectric patch for Configuration 1
Elements 4 and 5 form symmetric pair and similar voltage responses are observed in Figures 25.3 (d) and (e). Element 8 is symmetrically located with respect to element 1and a similar voltage response is predicted for it [see Figure 25.3 (a) and (f)].
