Abstract
Exact static analysis of 2-2 cement-based piezoelectric composites is presented based on the theory of piezo-elasticity in this paper. Displacement method was used, and the solutions of four different kinds of piezoelectric composites under load were obtained. The effects of polarization direction of piezoelectric layers and material parameters on the solutions are discussed. The relationship between the blocking force and the applied voltage for the actuators was obtained. The solutions were compared with both numerical and experimental results, and good agreement was found.
