Model-Based Guided Wave NDE: The Evolution of Guided Wave NDE from 'Magic' to 'Physically Based Engineering Tool'

摘要

The utility of those waves propagating over a distance, called "guided waves," provides abundant technical advantages in a variety of nondestructive evaluation (NDE) applications. In recent years, the field has rapidly grown as one of the most noticeable subjects in the NDE community, from not only the academic but also the practical standpoint, representing promising technological transfer. A number of commercialized inspection units and techniques are already available on the market. However, the principle of guided waves physics, which is crucial for proper usage and subsequent data analysis of the equipments has not been fully elucidated for field NDE engineers, and has mainly been set out for the purpose of simplifying the operation scheme.
