Abstract
This study focuses on exploiting the non-propagating modes of the ultrasonic guided waves in structural components, such as plates, trusses, beams, pipelines, and rails, which are ubiquitous in today’s civil infrastructural systems. These long-neglected localized modes are not currently used by state-of-the-art engineering practice. A thorough understanding of them and their interactions with various structural defects will lead to a new paradigm of ultrasound technology that can support early warning of structural integrity conditions.
