Synopsis

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.

Outcomes

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:

  • Characteristics of each method,
  • Theory & basic principles,
  • Advantages and disadvantages,
  • Selection and comparisons of techniques
  • Materials of parts that can be inspected (e.g. fibre-reinforced composites, metals and non-metals)
  • Physical size and/or shape limitations of parts,
  • Economics of the process,
  • Types of defects that can be detected and
  • 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:

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