Although many probabilistic models exist in literature, generally speaking, crack growth equations (linear, bi-linear) are too simplistic for real FCG calculations of mechanical components, most of whose live are spent in the near-threshold regime.
 This paper deals with the analysis of a probabilistic description of crack growth based on the so-called ‘NASGRO propagation equation’. First and foremost, it addresses a description of Virkler’s crack growth data, which shows a significant correlation between the parameters m, logC and ΔKth. The analysis is then applied to a set of crack growth data obtained from a steel applied in the manufacturing of railway axles.
