The researchers of the Faculty of Mechanical Engineering have published an article in Mechanical Systems and Signal Processing, one of the leading journals in the field of Mechanics Engineering (5/178, IF=8.4).
The study delves into the use of the thermoelastic principle to identify strain mode shapes in an Euler-Bernoulli beam. Utilizing a high-speed infrared (IR) camera, the researchers have proved that strain mode shapes can be accurately determined even when the noise floor surpasses the signal.
Such advancements not only improve the precision in locating critical fatigue hotspots in structures but also present a breakthrough in the field of strain experimental modal analysis (EMA). This research holds significant implications for assessing damage intensity and fatigue in diverse structural designs
