Keegan Moore, a University of Nebraska–Lincoln engineer, is on a mission to solve one of the most puzzling problems in mechanics: why bolts loosen over time. With a USD 727,410 (EUR 671,210) grant from the U.S. National Science Foundation, Moore is investigating the causes and solutions to this issue that has led to numerous accidents, from train derailments to oil spills.

Loose bolts pose a threat not only in high-profile accidents but also in everyday life, affecting school facilities, cars, and even the James Webb Space Telescope. Despite the widespread use of bolts, little is understood about how a structure's dynamics influence their loosening during normal operation.

Moore's research focuses on rotational loosening caused by vibrations. Using high-speed cameras and modeling frameworks, he aims to uncover how the interface contact conditions around the bolt hole change as the bolt loosens and the structure shakes. This could lead to predictive maintenance strategies that target specific problem areas, offering a more efficient approach to monitoring aging infrastructure.
