Present paper is a continuation of author’s earlier publications on stacking of piezoelectric plates. Analysis effects are presented by schemes received on the basis of computer calculations. The program is used for creation and analysis of graphical characteristics of piezoelectric plates. The application allows generation of graphs for a single piezoelectric plate as well as for complex systems. An additional advantage is the ability to obtain the 3D graphs, in which the test graph characterizes the plate not only in terms of frequency but can also include other parameters such as the thickness of the plate. The application is written in numerical software "Matlab" in such a way that it is possible to run a program on any computer without the installed software. A necessary condition for the correct operation of the program is availability of “MCR Matlab Compiler Runtime” free library.
