To address the significant limitation of existing non-destructive evaluation techniques in detecting and characterising early damage, this project aims to discover the physical nature of self-generated nonlinear waves by structural damage and to explore its potential for an entirely new class of non-destructive evaluation and structural health monitoring techniques. Major applications are expected to include a baseline-free structural health monitoring technique capable of detecting and quantifying barely-visible impact damage in advanced composite materials, non-destructive evaluation of structures made by additive manufacturing, and detection of hard-to-inspect locations in unitised structures.

为了解决现有的无损评估技术在检测和表征早期损伤方面的重大局限性，本项目旨在发现结构损伤自生非线性波的物理本质，并探索其作为一种全新的无损评估和结构健康监测技术的潜力。预计主要应用将包括无基线结构健康监测技术，能够检测和量化先进复合材料中几乎不可见的冲击损伤，对增材制造结构进行无损评估，以及检测组合结构中难以检查的位置。
