Description
Summary:The efficiency of two micromechanical models (the incremental self-consistent (ISC) and modified Eshelby–Mori–Tanaka (EMT)) is evaluated, in predicting the effective electroelastic properties of unidirectional piezoelectric polymer composites with an orthotropic polymeric matrix, especially at high volume fractions of reinforcement. The effective electroelastic properties of PZT-7A/PVDF composites were obtained using both the models and they were compared with those found using a representative volume element (RVE)-based finite-element (FE) model. Composites with two different types of connectivity and four different types of reinforcement geometry (spherical, ellipsoidal, circular cylindrical, and elliptic cylindrical) were considered. Our analysis showed that, in general, better results predicted the modified EMT model.
