© Published under licence by IOP Publishing Ltd.The urgency of the work consists in using a new approach to the definition of informative frequencies for the identification of corrosion damage. The aim of the work is to determine the discrepancies between the resonance frequencies of the oscillations of the fuel casing segments of the factory geometry and with various types of corrosion damage obtained by modelling defects in the casings of fuel casing segments. As a result of the analysis, informative ranges of ordinal numbers were revealed, which allow to determine the following corrosion damages: thinning from the outer and inner sides of the fuel casing, pitting corrosion, fretting corrosion.
