Probability Distribution Type for the Accumulated Damage from Miner's Rule in Fatigue Design

Variability is present within the stress-life (S-N) fatigue analysis process. This variability propagates through the analysis process into the accumulated damage computed using Miner’s Rule. This paper aims to characterise the probability distribution type of the accumulated damage from Miner’s rule when accounting for variability in fatigue design parameters using a case study. Whilst the distribution type could not be conclusively selected, considerations regarding the future application of probabilistic methods for fatigue design are presented.
