The proposed project promotes a conceptual advance in the application of plate waves for the quantitative reconstruction of laminar defects by investigating fundamental experimental and analytical aspects of a novel approach in plate wave ultrasonic tomography. A successful development will have a comparable significance in the area of health monitoring of thin structures as computer tomography had in medical imaging. Previous attempts have ignored wave scattering effects, and therefore do not describe the correct physics of the problem. With its combined experimental-numerical approach, the proposed fundamental studies will help to identify the potential of plate wave ultrasonic tomography for in-situ health monitoring of realistic structures and smart materials design.

该项目通过研究板波超声断层成像新方法的基本实验和分析方面，促进了板波在层状缺陷定量重建中的应用概念上的进步。一个成功的发展将在薄结构健康监测领域具有与计算机断层扫描在医学成像领域相当的意义。以前的尝试忽略了波散射效应，因此没有正确地描述问题的物理性质。通过实验与数值相结合的方法，所提出的基础研究将有助于确定板波超声层析成像在实际结构的原位健康监测和智能材料设计中的潜力。
