Second order strain tensor is equal to the inverse piezoelectric effect of electric field strength tensor multiplied by the vector. Our concern is linear strain, that is written in column matrix form of the strain tensor of the first 3 components, can be regarded as the column vector form: £ 1 (n) E2 (yy) £ 3 (hug) 1d2dlyd2d3EEE inverse piezoelectric effect midline strain is a function of electric field component. Simplified model, the common tubular PZT (lead zirconate titanate piezoelectric ceramic) of the axial deformation is proportional to the inverse piezoelectric effect of PZT coefficient d. And radial field strength (voltage divided by the wall thickness), also proportional to the length of the tube. The electrostrictive effect (electrostrictioneffct) of the linear strain is a quadratic function of the electric field: e1 (\tensor as a 3 on k multiplied by the EE. For example, I have measured the direction of a sheet material similar to electrostrictive strain is proportional to E (z direction proportional to the square of the applied voltage), and electric field E of symbols nothing. electrostrictive effect coefficient measuring coefficient than the inverse piezoelectric effect d4 (also known as the piezoelectric strain constant piezoelectricstrainontant) more difficult to measure. inverse piezoelectric effect is only produced in the piezoelectric body, it has a significant electrostrictive effect differences.
