Dr. Alex Ching-Tai NG Director of Graduate Studies, School
of Civil, Environmental and Mining Engineering, University of Adelaide,
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.
Alex Ching-Tai Ng is Director of Graduate Studies in Faculty of Engineering,
Computer and Mathematical Sciences, and Associate Professor in School of Civil
Environmental & Mining Engineering at The University of Adelaide. He
received his B.Eng and M.Phil from City University of Hong Kong, and Ph.D from The
University of Queensland.
research interest has been in the areas of structural health monitoring,
non-destructive testing, smart materials and structures, and vibration testing.
He leads a research group focusing on developments of guided wave and vibration
techniques for structural health monitoring and damage identification at The
University of Adelaide. He is Associate Editor and member of Executive
Committee for Structural Health Monitoring An International Journal, and
Associate Editor of Engineering Structures.
is an elected member of Executive Committee of Australian Network of Structural
Health Monitoring (ANSHM) and Council Member of International Society for
Structural Health Monitoring of Intelligent Infrastructures (ISHMII). He is
