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.

用压电效应法诊断聚碳酸酯整体破坏

提出了一种基于压电效应的透明单片聚碳酸酯断裂诊断方法。结果表明，在聚碳酸酯样品开始破坏之前，ΔU/U参数至少降低了10倍。结果表明，电极位置对压电电压的变化有影响。电极沿试样边缘的位置可以使压电电压与试样的反力对弯曲变形的一致性最好。
