According to recent research from the United States, "Sub-surface-initiated spalling, which is the classical mode of failure in rolling element bearings is significantly influenced by the inhomogeneous and stochastic nature of the material microstructure. This microstructural disorder is one of the primary reasons for scatter in fatigue lives for a seemingly identical batch of bearings."
"In this study, a stochastic fatigue model that takes the material microstructure explicitly into account is used to investigate dispersion in spalling lives for rolling element bearings. Material microstructures are generated stochastically using the process of Voronoi ...
