Department of Mechanical and Aerospace Engineering
- First semester 2018 (On-campus)
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:
- 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 principles.
- 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.
Continuous assessment: 50%
Final Examination (2 hours): 50%
Students are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.
3 hours lectures, 2 hours labs/tutorials and 7 hours of private study per week
