| Abstract: The aim of this work was to develop a methodology for the characterization of complex piezocomposites under external mechanical forces. In this specific procedure the samples were axially loaded in a universal mechanical test machine and monitored with an electrometer. The force versus displacement and the generated charge versus the applied force were measured. Cymbal piezocomposites were chosen due to their complex design which illustrated the effectiveness of the proposed methodology during the application of compression force loops. The occurrence of depolarization can be evaluated by measuring the electrical charge generated during the application of a compression loop. The results showed the dependence of electromechanical properties on both the PZT ceramics and the cymbal piezocomposite with the compressive load loops. The depolarization effect associated with the mechanical stress induced by switching of a non-180 degrees ferroelectric domain was evaluated. | |
