Technical Seminar on Ultrasonic Guided Waves for Nondestructive Evaluation of Structures

Date, time & venue
2019-10-17;6:00 pm – 6:30 pm (Refreshment), 6:30 pm – 7:30 pm (Talk);Chan Yat Mei Sophie Room – 9/F


Speakers: Dr. Alex Ching-Tai NG Director of Graduate Studies, School of Civil, Environmental and Mining Engineering, University of Adelaide, Australia.



Inspection of structures overs their lifetime to reduce life cycle costs, provide early detection of defects and improve reliability sustainability of structures is of vital importance in many engineering fields, such as civil, aerospace and mechanical engineering. Ultrasonic guided waves have been wide recognized as one of the effective and reliable techniques for non-destructive evaluation (NDE) and structural health monitoring (SHM) applications because of their high sensitivity to small and different types of defects, moderately large inspection ranges, and flexibility of implementing on structures through a wide range of standard and built-in transducers. The talk provides an overview of studies and techniques devoted to developments of ultrasonic guided wave for NDE and SHM. Different examples on using ultrasonic guided waves are given to illustrate their capability and applications. The talk will first focus on linear ultrasonic guided waves and then focus on recent developments on using nonlinear ultrasonic guided waves.
