Development of a Nondestructive Imaging Tool to Identify Deficiencies in External Tendons Containing Flexible Fillers

The technical goal of this work is to modify the design of unit hardware and software for application to detection in wax-filled external post-tensioned tendons. The modification will be informed through modeling and experimental efforts to identify optimal operating parameters (frequency range, amplitude, sensor type and size, etc.) that maximize the sensitivity of TIU for detection of filler deficiencies within wax-filled external tendons.
