The potential benefit of structural health monitoring is highlighted by the socio-economic impact of structural failure, which may result in loss of lives, infrastructure disruptions and loss of productivity. This proposal promotes a fundamental advance in the novel concept of ultrasonic diffraction tomography for imaging early stage structural damage in plates. The successful development will represent an essential advance in quantitative non-destructive evaluation of thin structures and enable the transition of the technique to realistic structures with all the potential benefits in mechanical and civil infrastructure management resulting in improved safety, reduced maintenance costs and the use of more efficient structural designs.

结构故障的社会经济影响突出了结构健康监测的潜在好处，结构故障可能导致生命损失、基础设施中断和生产力损失。这一建议促进了超声衍射层析成像新概念的根本性进展，该概念用于成像板的早期结构损伤。这一成功的开发将代表着薄结构定量无损评估方面的重大进步，并使该技术能够过渡到现实结构，在机械和民用基础设施管理方面具有所有潜在好处，从而提高安全性，降低维护成本，并使用更有效的结构设计。
