Abstract

The present work addresses the propagation characteristics of Lamb wave in a piezoelectric fiber-reinforced composite material plate. The considered plate is micro-mechanically modeled using the analytical techniques of the Strength of Materials and Rule of Mixtures. Secular equations are deduced for symmetric and antisymmetric modes of Lamb wave by employing suitable boundary conditions. The data of two distinct PFRC materials are taken into account, viz. PZT-5A-epoxy and CdSe-epoxy with different fiber volume fractions to investigate the latent characteristics of Lamb wave propagation. The amplitudes of dilatation and electrical potential of considered material are examined numerically and manifested graphically for both kinds of modes, i.e., symmetric and antisymmetric modes. The obtained graphical results are also compared for both kinds of modes. A comparative study has been carried out to exhibit the concealed characteristics of Lamb wave propagation for various distinct cases of considered structure for both symmetric and antisymmetric modes. The determined analytical results are in well agreement with the results present in the existing literature.

微机械压电纤维增强复合板中的 Lamb 波传输

本研究探讨了压电纤维增强复合材料板中的兰姆波传播特性。使用材料强度和混合物规则的分析技术对所考虑的板进行了微观力学建模。通过采用合适的边界条件，推导出了对称和非对称模式的兰姆波周期方程。考虑了两种不同 PFRC 材料的数据，即具有不同纤维体积分数的 PZT-5A-epoxy 和 CdSe-epoxy，以研究 Lamb 波传播的潜伏特性。对于两种模式，即对称模式和非对称模式，对所考虑材料的扩张幅度和电动势进行了数值和图形分析。还对两种模式的图形结果进行了比较。对比研究显示了对称和非对称两种模式下各种不同情况下考虑结构的 Lamb 波传播隐蔽特性。确定的分析结果与现有文献中的结果完全一致。

期刊介绍： Wave Motion is devoted to the cross fertilization of ideas, and to stimulating interaction between workers in various research areas in which wave propagation phenomena play a dominant role. The description and analysis of wave propagation phenomena provides a unifying thread connecting diverse areas of engineering and the physical sciences such as acoustics, optics, geophysics, seismology, electromagnetic theory, solid and fluid mechanics. The journal publishes papers on analytical, numerical and experimental methods. Papers that address fundamentally new topics in wave phenomena or develop wave propagation methods for solving direct and inverse problems are of interest to the journal.
