Finite element analysis (FEA) is a modern tool for exploration of new horizons in science, technology and engineering. Different computer software such as ANSYS, ABACUS, PZFLEX and COMSOL Multiphysics® based on FEA are used for modeling and simulation of acoustic phenomena, for design of new and optimization and improvement of existing acoustic engineering systems. This work presents application of FEA to modeling and simulation of different types of piezoelectric materials, including some new and promising ones such as piezo crystals PMN-PT and PIN-PMN-PT.

This work gives a comparison between experimental and modeling data for different types of piezoelectric materials with analysis of their effectiveness and efficiency. Graphs demonstrate significant elevations of mechanical displacements for PIN-PMN-PT piezoelectric crystals.
