本文基于作者在ICU-2015上的报告，给出了半解析积分方程方法的想法，以物理上清晰地模拟具有局部不均匀性的复合板状结构中的波动现象。在此基础上，开发了一套用于可靠的近场和远场分析的低成本计算机模型，并进行了实验验证。他们的能力已经说明了与压电晶片有源传感器（PWAS）产生的导波（GW）的结构频率响应和辐射图案图的例子;纤维增强复合材料的有效弹性模量的重建; PWAS频率调谐与会计引起的各向异性的辐射方向性;和波能量共振传输和捕获的影响。其中一些例子已经在期刊文章中讨论过。因此，本文集中在最近的结果谐振GW与深表面切口和埋腔相互作用。
The paper is based on the authors’ report at ICU-2015 giving the idea of the semi-analytical integral equation approach to a physically clear simulation of wave phenomena in composite plate-like structures with local inhomogeneities. On this basis, a set of low-cost computer models for a reliable near- and far-field analysis had been developed and experimentally validated. Their abilities have been illustrated with examples of structural frequency response and radiation pattern diagrams for guided waves (GW) generated by piezoelectric wafer active sensors (PWAS); the reconstruction of effective elastic moduli of fiber-reinforced composites; the PWAS frequency tuning with accounting for the radiation directivity induced by anisotropy; and the effects of wave energy resonance transmission and trapping. Some of these examples have been already discussed in journal articles. Therefore, the present paper concentrates on the recent results of resonance GW interaction with deep surface notches and buried cavities.
