| One of the techniques applicable to assess the condition of multi-layered, hybrid structures is ultrasonic testing (UT). Essentially, a complex signal is received, which is typically processed using advanced signal processing techniques. However, some of these methods are not fully compatible with all types of structures or are prone to errors due to improper adjustments. Therefore, this paper proposes a novel mathematical approach to automate defect detection in fibre-metal laminates (FMLs). This approach offers advantages over traditional UT methods by providing concise numerical signal features as an aggregate, separated by elements, and showing relationships between these elements. Additionally, it is insensitive to UT equipment parameters and can be easily applied to various structural types, especially FMLs. The method, validated on real ultrasonic signals from fibre-metal laminates, achieves high accuracy in distinguishing defective areas from healthy ones through a significant difference in descriptor values below and above an adjustable threshold value. |
