Research and development of magnetic non-destructive testing techniques

In high-impact fields such as the oil and gas and nuclear industries, the consequences of failures can be catastrophic. My work involves the development of magnetic non-destructive evaluation (NDE) techniques to detect areas of localized high strain which threaten the integrity and safe operation of engineering systems. Techniques based on magnetism are the best suited to strain measurement, since other methods (e.g. eddy current, ultrasonic) are much less strain sensitive. However, the correlation between magnetic behaviour and strain is very complex in engineering materials and not well understood. This Discovery grant funding will further my long term goals of understanding and exploiting the magnetic response of strain in ferromagnetic engineering materials.
