N. Petrone et alii, Frattura ed Integrità Strutturale, 30 (2014) 226-236; DOI: 10.3221/IGF-ESIS.30.29 231 static tests. The results of this analysis have been collected for four channels in Tab. 2 and 3. The MAX and MIN values correspond to the positive and negative peaks recorded during the event (bumps & braking) or the portions of tracks that were recognized as representing the different surfaces and conditions (1 person or 2 persons). RNG values correspond to the maximum range values recorded during the considered track portion and correspond to the largest cycles that the components underwent during their recorded fatigue life history. Events with the largest ranges are reported as bold in the table. AVE correspond to the mean values recorded during the track portion, as well as STD correspond to the standard deviation from the track portion.
