Biography
Dr Fan is currently an assistant professor in school of Mechanical and Aerospace Engineering at Nanyang Technological University. He obtained his PhD degree at Imperial College London, specialized in Non-Destructive Evaluation. Dr Fan’s research motivation is solve real inspection and monitoring problems in industry, achieved by conducting thorough scientific research. He has been involved in NDE research for 10 years, and he has extensive knowledge of cutting edge NDE technologies especially in ultrasound. His research focus is to develop novel NDE techniques for metal and composite inspection, structure health monitoring and material characterization, by integrating physics and modeling techniques with the development of rapidly exploitable technologies. He has collaborated with varies industries including Rolls-Royce, Shell, Petrobras, ABS, E.ON, EDF, etc for different research and consultancy projects. His research work has gained worldwide recognition, and he has won “Bob Chiver’s Prize” from Institute of Physics in the UK.

Research
  • Interest:
    large area inspection using ultrasonic screening technology, structure health monitoring techniques, high resolution in NDT using advance signal processing methods and simulation and modelling of NDT/SHM techniques
  • Projects:
    Numerical Modelling of Corrosion Mapping in Ship Structures Using Ultrasonic Guided Waves
    Corrosion damage is a major issue in ship industries, costing billions of dollars every year, this project aims to develop an innovative method to inspect or monitor the corrosion damage using ultrasonic guided waves.
    [Mechanics of Machines Lab, Mechanics]
    Numerical simulation for advanced weld screening techniques for fatigue damages using ultrasonic welded guided waves
    This project aims to develop a novel ultrasonic screening technology to access the integrity of long welds, which will Significantly reduce the time and cost of weld inspection and also provide a solution to non-accessible areas.
    [Mechanics of Machines Lab, Mechanics]
    Non-Destructive Online Measurement of Residual Stress in Sub-Surface Processes
    This project aims to investigate advanced non-destructive methods to assess the thickness profile of residual stress in sub-surface process.
    [Mechanics of Machines Lab, Mechanics]
    Advanced defect sizing in composite laminated structures via a refined ultrasonic Lamb wave technique
    Future generations of passenger aircraft will incorporate significantly increasing fractions of composite materials, because of their high strength to weight ratio. This brings new challenges in the non-destructive evaluation of the structure throughout its service life. This project aims to investigate the possibility of using ultrasonic guided wave to detect and size defects in composite laminated structures, especially those with complex geometries.
