This paper presents a new methodology for noncontact measurement of the axial force of bolts in their tightening processes using laser-generated ultrasound waves. This method employs ultrasound waves scattered in a bolt shaft to detect axial force ch...

Imaging Microstructure on Optically Rough Surfaces Using Spatially Resolved Acoustic Spectroscopy (2023)
Journal Article
Li, W., Dryburgh, P., Pieris, D., Patel, R., Clark, M., & Smith, R. J. (2023). Imaging Microstructure on Optically Rough Surfaces Using Spatially Resolved Acoustic Spectroscopy. Applied Sciences, 13(6), Article 3424. https://doi.org/10.3390/app13063424

The microstructure of a material defines many of its mechanical properties. Tracking the microstructure of parts during their manufacturing is needed to ensure the designed performance can be obtained, especially for additively manufactured parts. Me...
