项目摘要

Ageing infrastructure and the move towards more advanced materials raises new, currently unsolved, inspection challenges. Fatigue and creep damage are two of the most common modes of failure in engineering structures, yet both are extremely difficult to detect in early stages of development. Similarly, there is a growing need to inspect bonded joints, be it adhesively bonded composites for major engineering components, or diffusion bonded metal components such as super-plastically deformed fan blades. This lack of inspection technique is artificially limiting the lifetimes and use of engineering components and was recently highlighted as a key requirement on the 5-10 year horizon by a group of industrial end-users of Non-Destructive Evaluation (NDE). They specifically highlighted the need for ``techniques identified for crack precursors, difficult and new engineering materials''.This fellowship will enable the applicant to develop practical and deployable nonlinear ultrasonic inspection techniques for monitoring of each of these damage scenarios, making use of recent developments in ultrasonic equipment, specifically highly flexible phased array systems and novel experimental techniques. The use of phased arrays, which are specifically tailored for NDE, is key. They allow multiple measurements without sensor repositioning, eliminating the high coupling and alignment variability that can readily mask the extremely small nonlinear signals. Even more importantly, the approach in this fellowship will enable localisation of nonlinearity within a specimen. This is currently not possible with any degree of reliability and represents a key barrier to wider adoption of this exciting inspection approach.
老化的基础设施和向更先进材料的转变提出了新的、目前尚未解决的检验挑战。疲劳和蠕变损伤是工程结构中最常见的两种破坏模式,但在开发的早期阶段,这两种破坏模式都极难检测到。同样,检测粘合接头的需求也在不断增长,无论是用于主要工程部件的粘合复合材料,还是扩散粘合金属部件(如超塑性变形风扇叶片)。这种检测技术的缺乏人为地限制了工程部件的使用寿命和使用,并且最近被一组无损评估(NDE)的工业最终用户强调为5-10年的关键要求。他们特别强调需要“识别裂纹前体、困难和新工程材料的技术”。该奖学金将使申请人能够利用超声设备的最新发展,特别是高度灵活的相控阵系统和新颖的实验技术,开发实用和可部署的非线性超声检测技术,以监测这些损伤情况。使用专门为无损检测量身定制的相控阵是关键。它们允许多次测量而无需传感器重新定位,消除了高耦合和对准可变性,可以很容易地掩盖极小的非线性信号。更重要的是,本研究中的方法将使标本内非线性的局部化成为可能。目前,这在任何程度的可靠性上都是不可能的,这是广泛采用这种令人兴奋的检测方法的一个关键障碍。
