Intelligent Material Systems Approach to Qualitative Non-Destructive Evaluation of Civil Infrastructure

研究工作的目的是发展对最近开发的定性无损评估传感器系统的基本科学方面的理解。它依赖于跟踪结构的高频（通常为50 KHz）点阻抗来识别损伤。在如此高的频率下，该技术的灵敏度可与最复杂的传统濒死技术（如超声波）相媲美，并且能够通过观察结构阻抗的变化来定性地检测早期类型的损伤。该技术克服了模型和“低频”濒死体验方法的所有关键限制

I relies on tracking the high-frequency(typically 50 KHz) pointimpedance of the structure to identify damange. At such high frequencies, the techniques such as comparable in sensitivity to the most sophisticated traditional NDE techniques such as ultrasonics and is capable of qualitiatively detecting incipient type damage by looking at changes in structural impedance. This technique overcomes all of the critical limitations of model and "low frequency" NDE approaches
