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.

在石油、天然气和核工业等高影响领域，故障的后果可能是灾难性的。 我的工作涉及磁性无损评估（NDE）技术的发展，以检测局部高应变区域，这些区域威胁到工程系统的完整性和安全运行。 基于磁性的技术最适合应变测量，因为其他方法（例如涡流，超声波）对应变的敏感性要低得多。 然而，在工程材料中，磁行为和应变之间的相关性非常复杂，并且尚未得到很好的理解。 这项发现基金将进一步推动我的长期目标，即理解和利用铁磁工程材料中应变的磁响应。
