The macroscopic piezo-electroelastic properties of piezoelectric particles-dispersed composites are affected by the geometric scatter of particles. In this study, a multi-scale finite element analysis based on homogenization method is proposed to estimate the macroscopic piezo-electroelastic properties considering the geometric scatter of particles. As an example, the effects of scatters in diameter and aspect ratio of particle have been investigated numerically for piezoelectric composite consisting of PZT particles and epoxy resin. It was recognized that the scatter of diameter has lager influence on macroscopic properties than one of aspect ratio.
