SUMMARY
The discussion centers on understanding the d31 and d33 strain coefficients related to PZT (lead zirconate titanate) actuated membranes. The numbers 31 and 33 refer to specific directions in the piezoelectric tensor, where '1' typically denotes elongation and '3' denotes shear. These coefficients are not arbitrary; they are predefined for PZT actuators and are essential for applying the correct values in relevant equations. A clear understanding of these coefficients is crucial for interpreting related research papers effectively.
