Paper Abstract

Non-destructive Testing and Evaluation (NDT&E) is critical in the safety assurance of modern engineering structures, particularly when using high performance materials. Frequently, such materials are subject to mechanisms of damage uncommon in conventional structures. Additionally, many high performance alloys such as advanced aerospace aluminiums are more susceptible to fatigue failure than more traditional metals. In all such cases, it is essential to have good knowledge of the defects present in a component in order to assess its soundness. One of the most common and verstaile techniques used in NDT&E is ultrasonic testing, where the integrity of a component is characterized using acoustic waves.
