Abstract- In this paper, the application of piezoelectric actuators to the composite control card is studied statically. The electro-thermo-mechanically coupled mathematical model is used for the analysis. The main section of this paper is static control. Shape control is stated here as determining the shape control parameters, including the actuation voltage and the adjustment of the actuator orientation, so that the structure which is activated using these parameters also adapts as closely as possible to the required shape. In this paper, we have presented FE model for the control analysis of the shape of piezoelectric laminated (PZT) composite plates using Ansys. The piezoelectric layer and composite plate are modeled in the form of additional layers to be attached to the upper or lower surface or to be integrated into the laminated composite plate. Ansys finite element software is used for modeling and has been successfully validated with experimental and numerical results which are readily available in the literature. The present analysis shows that with the application of an appropriate voltage to the piezoelectric actuator, the desired shape of the composite plate can be obtained.
