  • First semester 2017 (Day)


This unit explores various established techniques such as dye penetration, magnetic particle, eddy current, ultrasonic and radiography for non-destructive testing (NDT) and contrasts them with destructive methods. Industry standards for NDT and acceptance standards will be included. Case studies from a variety of industries which include microelectronics, aerospace, marine, railway and petrochemical industries will be discussed.


This unit aims to develop an in-depth understanding of the working principles associated with established and widely used techniques for non-destructive testing (NDT), specifically dye penetration, magnetic particle, eddy current, ultrasonic and radiography. For each method the following will be studied:

  1. Characteristics of each method,
  2. Theory & basic principles,
  3. Advantages and disadvantages,
  4. Selection and comparisons of techniques
  5. Materials of parts that can be inspected (e.g. fibre-reinforced composites, metals and non-metals)
  6. Physical size and/or shape limitations of parts,
  7. Economics of the process,
  8. Types of defects that can be detected and
  9. Ability and accuracy, with which defects can be located, sized, and their orientation and shape characteristics determined.

    Specifically, the unit aims to develop the ability to:

  10. Relate the capabilities and limitations of established NDT techniques to their respective basic working principles.
  11. Evaluate the various NDT methods for flaw detection and damage assessment and be able to select the appropriate technique for a given scenario.
  12. Perform data acquisition and signal analysis related to NDT techniques and use these results to predict the health and integrity of the test specimen.
