Description/Abstract

Piezoelectric composites with 1-3 connectivity are an important class of materials for underwater acoustics and biomedical imaging. Their dependence on the electromechanical properties and geometry of the piezoelectric rods creates an opportunity for tailoring its performance according to the design requirements. In this paper, we study the effects of the variation in the polarization orientation on the performance of 1-3 piezoelectric composites. The micromechanics based Mori-Tanaka model for piezoelectric composite is used to determine the electromechanical moduli of the composites. Results show that the polarization orientations significantly affect the performance of the piezoelectric composite. These results can provide useful information for optimizing the design of 1-3 piezoelectric composites for specific applications.
