Abstract

The use of thin magnetostrictive patches to generate and detect guided waves within the composite samples is investigated for defect detection. This approach has been implemented using SH0 shear horizontal guided waves in both CFRP and GFRP plates. A magnetostrictive patch transducer was able to generate SH0 waves with known directional characteristics. The synthetic aperture focusing technique (SAFT) was then used to reconstruct images of defects using multiple transmission and detection locations. The results for imaging defects in both types of material are presented.

摘要

研究了使用薄磁致伸缩贴片在复合材料样品中产生和检测导波，以进行缺陷检测。这种方法已经在 CFRP 和 GFRP 板中使用 SH0 剪切水平导波实现。磁致伸缩贴片换能器能够产生具有已知方向特性的 SH0 波。然后使用合成孔径聚焦技术 (SAFT) 使用多个传输和检测位置来重建缺陷图像。给出了两种材料中成像缺陷的结果。
