Wave Propagation in Multi-layered Aircraft Components
Based on experience starting from my PhD thesis at ETH Z├╝rich, fundamental contributions to the understanding of mechanical wave propagation and scattering by combining advanced experimental, numerical, and analytical methods have been one of the focal points of my research. During this project, starting from the physical understanding of guided ultrasonic wave propagation in multi-layered structures, semi-analytical and numerical models to describe the underlying mechanics have been developed. The significant, step change is to bridge the gap from theory to application and to work on real, complex, multi-layered aircraft structures, investigating ways to deal with the complexity of the guided wave propagation and scattering. Aircraft are safety-critical structures, where adverse operating conditions can lead to the development of faults during the lifecycle of the structure, especially fatigue damage. This damage can lead to the malfunction and ultimately failure of such structures, endangering lives. Therefore the integrity of such structures needs to be tested regularly or monitored. In collaboration with Airbus UK the developed technology will be applied to manufactured aircraft structures, and practical application experience gained, demonstrating the potential for the increase of inherent safety. The novel demonstrated methodology will enable the rapid and cost-efficient inspection and permanent monitoring of large surface areas of complex technical structures using guided ultrasonic waves.
