Structural health monitoring (SHM) offers the prospect of a quantum gain in performance and efficiency for the design and structural integrity management of high-value assets (e.g. aircraft). The aims of this project are to develop and validate efficient computational tools for: (i) Characterising the scattering of the Lamb waves by defects or boundaries, and (ii) Implementing robust and versatile approaches to tomographic imaging of laminar defects or damage from experimental/synthetic scattered field data. This project will result in the development of a validated and versatile SHM system for quantifying damage that is analogous to computerised tomography in medical imaging.

结构健康监测 (SHM) 为高价值资产（例如飞机）的设计和结构完整性管理提供了性能和效率大幅提升的前景。该项目的目标是开发和验证高效的计算工具： (i) 通过缺陷或边界表征兰姆波的散射，以及 (ii) 实施稳健且通用的方法，根据实验/合成散射场数据对层状缺陷或损坏进行层析成像。 该项目将开发出一种经过验证的多功能 SHM 系统，用于量化损伤，类似于医学成像中的计算机断层扫描。
