Robert Basan et al. / Procedia Structural Integrity 68 (2025) 782–787 R. Basan et al. / Structural Integrity Procedia 00 (2025) 000–000 in low-cycle and high-cycle fatigue regimes separately. The established evaluation methodology also enables direct comparison with results of earlier evaluation studies reported in literature, Park and Song (1995), J ��� a � d S �� g ( 2002) a � d L �� a � d S �� g ( 2006) . From determined values of evaluation criteria, rather inconsistent performance and accuracy across different ultimate strengths and fatigue regimes is noticeable. Although it can be concluded from the obtained results that Uniform Material Law and FKM Method performed best for aluminum alloys, and that Medians Method is best for titanium alloys, none of those methods can really be recommended. More comprehensive analyses and evaluations are warranted including also other estimation methods (Original Universal Slopes Method, Four-Point Correlation Method, Modified Universal Slopes Method, Modified Four-Point Correlation Method, Modified Method by Mitchell) and additional material datasets. This is expected to result in more detailed and substantial information on performance and suitability of individual methods for estimation of fatigue parameters of aluminum and titanium alloys and will be published in an extended form.
