Abstract
The hydrostatic piezoelectric charge coefficients (d(h)) and hydrostat ic piezoelectric voltage coefficients (g(h)) of 1-3 PZT/polymer compos ites have been calculated by two equations containing the stress tenso rs of each element. A composite model is divided into 162 elements, an d the stress distributions are computed under 0.7 MPa hydrostatic pres sure using the finite-element method. The higher d(h) value is found f or the composite with 30.9% PZT and the higher g(h) value for the comp osite with 19.8% PZT.
