|All Constitutive Forms|
|The four possible forms for piezoelectric constitutive equations are shown below. The names for each of the forms is arbitrary; they were taken from the two dependent variables on the left-hand-side of each equation. Note that the Voltage and Electric Field variables are related via a gradient.|
|Strain-Charge Form:||Stress-Charge Form:|
|Strain-Voltage Form:||Stress-Voltage Form:|
|Matrix transformations for converting piezoelectric constitutive data from one form into another form are shown below. Only 4 out of the 6 possible combinations are shown.|
|Strain-Charge to Stress-Charge:||Strain-Charge to Strain-Voltage:|
|Stress-Charge to Stress-Voltage:||Strain-Voltage to Stress-Voltage:|
