Abstract [en]

Resonant ultrasound spectroscopy (RUS) is a non-destructive technique originally developed for evaluating elastic constants of solids using resonance frequencies corresponding to the normal modes of vibration observed in samples with regular geometry. RUS can also be used for non-destructive evaluation of various metal or ceramic objects based on their resonance spectra. RUS can be used to detect deviations such as variations in dimensions and hardness or flaws in the inspected objects. This paper presents an application of RUS for monitoring the hardness of steel rings. Experimental results are presented that show a correlation between the shift of the resonant frequencies and the hardness of the inspected steel rings.
