The presence of the elements, which work as sensors or actuators, is one of the main features of smart-constructions. These elements are commonly made of piezoelectric materials, the main feature of which is a direct and inverse piezoelectric effect, which allows its functioning as a sensor and actuator. In addition, one and the same element can combine both functions. Moreover electroding of surfaces of the piezoelectric elements provides an additional means of controlling the dynamic processes due to application of different electric circuits connected to piezoelectric elements. The location of the piezoelectric element, its size and geometry play a significant role in damping the vibration of structures containing elements made of piezoelectric materials. In this paper, a comparative analysis of different possible options of smart-function realization is made by comparing the patterns of strains and electric potentials generated on the piezoelectric element surface. The numerical results of determining the optimal piezoelectric element location, which will provide the generation of maximal electric potential at certain resonant frequencies, are presented. The numerical implementation is carried out by the finite element method using the commercial ANSYS software package.
