The goal of the study was to verify a finite element model of the piezoelectric element by comparing results of numerical simulations with those obtained experimentally. The stand used in the experiment consists of the piezoelectric element, which was excited by the voltage supplied or the attached static force. The piezoelectric patch relative displacement measured between two points was measured by the inductive displacement sensor. The finite element model was built in ANSYS software. The plates and piezoelectric patch were modeled by the eight node elements with an additional electric degree of freedom for piezoelectric element. A full piezoelectric matrix was used in the finite element analysis instead of a one-dimensional piezoelectric effect, which dominates in many analytical approaches. It allowed building a more accurate model of the system. The experimental tests and finite element method simulations were performed and acquired results were compared. The characteristics of the piezoelectric patch displacement were shown and discussed.
