本文考虑了夹杂物之间的相互作用，导出了0-3复合材料有效压电系数（d31和d33）的两个显式公式，并直接用组分的性质表示。使用这两个公式的预测进行了比较，与已公布的实验数据的0-3复合系统具有三种不同的极化状态：只有夹杂物相是极化，两个阶段是在同一方向上极化和两个阶段是在相反的方向上极化。此外，使用Wong et al.等人的方案（Wong CK，Poon YM，Shin FG（2001）J Appl Phys 90：4690）和Furukawa等人的方案（Wong CK，Poon YM，Shin FG（2001）J Appl Phys 90：4690）。的模型（Furukawa T，Fujino K，Jakada E（1976）Jpn J Appl Phys 15：2119）用于比较。对于前两种情况，结果表明，我们的模型和Wong et al.的方案具有可比的性能。然而，对于最后一种情况，我们的模型给出了比他们更有利的预测。
Two explicit formulae for the effective piezoelectric coefficients (d31andd33) of 0–3 composite have been derived by taking into account the interaction effects between the inclusions and are expressed directly in terms of the properties of the constituents. Predictions using these two formulae are compared with published experimental data of 0–3 composite systems having three different polarization states: only the inclusion phase is polarized; both phases are polarized in the same direction and the two phases are polarized in opposite directions. In addition, the predictions using Wong et al.’s scheme (Wong CK, Poon YM, Shin FG (2001) J Appl Phys 90:4690) and Furukawa et al.’s model (Furukawa T, Fujino K, Fukada E (1976) Jpn J Appl Phys 15:2119) are included for comparison. For the first two cases, the results show that both our model and Wong et al.’s scheme have comparable performance. However, for the last case, our model gives more favorable predictions than theirs.
