Abstract

An approach to transparent monolithic polycarbonate fracture diagnostics based on the piezoelectric effect is considered. It was shown that the ΔU/U parameter decreases by at least 10 times before the polycarbonate sample begins to be destroyed. It was shown that the electrodes location influence the changes in the piezoelectric voltage. The location of electrodes along the edge of the sample can provide the best conformity between the piezoelectric voltage and the reaction force of the sample to bending deformation.
