超声导波在结构完整性管理方面具有广阔的前景，但由于其复杂的机制，仍有很多需要了解的地方。缺陷尺寸或量化对于使用超声导波进行结构检测非常重要，而这个反问题也很难解决。本文提出的工作旨在解决使用兰姆波检测薄弹性板时的横向裂纹量化问题。首先，采用二维（2D）边界元法（BEM）模拟来研究一种选定的纯模式兰姆波与横向裂纹缺陷的相互作用，并将其定义为正演问题。然后根据数值模拟的结果构建反射和透射系数表面。最后，提出了一种基于这些反射和透射系数表面的横向裂纹量化方法。量化示例表明所提出的方法具有可接受的准确性。还讨论了这种方法的一些局限性。
Ultrasonic guided wave is promising in structure integrity management, but there is still much to learn about it because of its complex mechanism. Defect sizing or quantification is very important for structure inspection using ultrasonic guided waves, and this inverse problem is also very difficult to solve. The work presented in this article aims to resolve the lateral crack quantification problem in the inspection of thin elastic plate using Lamb wave. First, two-dimensional (2D) boundary element method (BEM) simulation was used to study the interaction of one chosen pure mode Lamb wave with lateral crack defect, and this could be defined as the forward problem. Then reflection and transmission coefficients surfaces were built from the results of the numerical simulation. Finally, an approach for lateral crack quantification based on these reflection and transmission coefficients surfaces was proposed. The quantification examples show that the presented approach gives acceptable accuracy. Some limitations of this approach are also discussed.
