Modeling of laminated composite structures with piezoelectric actuators

The objective of this paper is to develop the modeling of adaptive composite structures for active vibration control. The first order shear deformation beam theory is used for the analysis to ensure accurate bending solutions. Experimental, theoretical and numerical modeling approaches are conducted into the active vibration control of laminate beam structures with bonded and embedded piezoelectric actuators. The modeling of the dynamic response of composite structures is presented. A modal analysis is performed to determine the natural frequencies and mode shapes of the structures. The natural frequency results obtained by the assumed-modes method and the theoretical solutions are validated through the experimental results obtained from 151 and finite elements. The assumed-modes method can accurately predict the natural frequencies and mode shape of the laminate beam. Finally, the effects of the number and locations of the actuators on the control system are also investigated using a static analysis of the model.
