This project aims to investigate new approaches for frequency mixing in nonlinear ultrasonics, and to demonstrate their potential for the non-destructive evaluation of material degradation and early damage detection. The anticipated outcomes will be increased detection sensitivity relative to current inspection techniques and an enhanced capability for quantifying the damage. This will provide the basis for more cost efficient safety management of high-value assets and infrastructure, and for enhancing Australia’s competitiveness in advanced manufacturing.

该项目旨在研究非线性超声中频率混合的新方法，并展示其在材料退化和早期损伤检测的非破坏性评估中的潜力。预期的成果将是相对于目前的检查技术提高探测灵敏度，并增强量化损害的能力。这将为高价值资产和基础设施的更具成本效益的安全管理提供基础，并提高澳大利亚在先进制造业中的竞争力。
