Abstract This paper is a follow-up to the Plantema Memorial Lecture that was presented by the author at the ICAF 2017 Symposium at Nagoya, Japan (Brot 2017). It will be shown in this paper, that there may be very large differences between the Weibull and Log-Normal statistical distributions of fatigue test results. These large differences have been confirmed using special software, that is commercially available. Fatigue test data from several sources have been combined to result in an 86-specimen database of fatigue life results. Analysis of these test results, using the software indicated above, determined that the Weibull distribution gave much more suitable results than the Log-Normal distribution.
