Abstract In this paper, a hybrid finite element is proposed for modeling in a spatial setting of coupled thermoelectromechanical fields in composite plates with piezoelectric patches, based on the method of reference surfaces. According to the method of reference surfaces, reference surfaces parallel to the middle surface are selected in the layers of the plate and piezoelectric patches to be introduced as the sought functions of temperature, displacements and electric potentials of these surfaces. First, the temperature distribution in the laminated plate is calculated by solving the heat conduction problem by the finite element method. The results obtained are used as input data for solving the problem of thermoelectroelasticity. On the basis of the developed finite element model, a method is proposed for determining the optimal electric potentials supplied to the electrodes of the actuators in order to bring the plate to a given shape by using the inverse piezoelectric effect.
