Abstract

The effect of the location and thickness of twin collocated piezoelectric actuators embedded in a composite structure is analytically studied. An expression for the effective moment induced by the actuators is derived using a static analysis assuming perfect bonding (i.e., zero bonding thickness). The optimal actuator position and thickness which maximizes piezoactuator/substructure coupling is investigated for various actuators/substructure combinations. Results of this study show that the optimal actuator location is at the surface of the composite when the Young's modulus of the actuator is less than approximately 3 to 5 times the modulus of the substructure. However, when the modulus of the actuator is much greater than the substructure, the optimal location of the actuators is within the composite rather than at the surface.
