摘　　要：In this paper,we investigate the effective properties of three-phase(matrix/coating/fiber)cylindrical piezoelectric composites with imperfect interfaces under anti-plane mechanical and in-plane electrical loads.By using the electromechanically coupling spring-type interface model and the generalized self-consistent method(GSM),we analytically derived the effective electroelastic moduli.The present solutions include as special cases the three-phase cylindrical piezoelectric composites with perfect interfaces as well as the two-phase(matrix/fiber)case with imperfect or perfect interfaces.Selected calculations are graphically shown to demonstrate dependence of the effective moduli on the interfacial properties.The particular size-dependent characteristic due to the interfacial imperfection is also discussed.
