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（如飞机）的设计和结构完整性管理提供了性能和效率方面的量子增益的前景。该项目的目的是开发和验证有效的计算工具，用于： (i)表征缺陷或边界对兰姆波的散射，以及 (ii)通过实验/合成散射场数据，实现对层状缺陷或损伤进行断层成像的稳健和通用方法。 该项目将导致开发一种经过验证的多功能SHM系统，用于量化类似于医学成像中的计算机断层扫描的损伤。
