Abstract
Piezoelectric actuators are one of the smart/intelligent materials which can be used as "Induced Strain Actuators" for structural members like beams, plates and shells. These piezoelectric actuators (PZT) can be bonded or embedded in the structure. The adhesive bonding between the piezoceramics and the substrate could significantly affect the strain transfer from the actuator to the substrate. The present work is an effort in experimental characterization of piezoelectric actuation of beams. A cantilever beam with surface bonded piezoelectric actuators is considered. In order to observe the effect of adhesive properties, three different adhesives viz. cyano-acrylate, epoxy resin and a structural film adhesive are used. Experiments are performed on these specimens with piezo patches in series as well as in parallel configurations, over complete cycles of the applied field. The experimental findings are compared with an existing two-dimensional Finite Element model. It is observed that cyano-acrylate bonding is the closest to the perfect bonding case. It is also observed that piezoelectric actuation exhibits significant hysterisis.
