The aim of the work was the selection of the most suitable method for fracture surface analysis using modern tools for mathematical verification of a dataset containing irregular data values and considerable variability of amplitude. The Hurst exponent was used for the verification of the analyzed dataset. The proposed procedure for the Hurst exponent calculations was verified for the profiles obtained from the fracture surface of 18G2A steel and pure iron in the rough state and after wavelet approximations.
