Nick Weinzapfel, Auteur ; Farshid Sadeghi, Auteur ; Alexander Liebel, Auteur |Rolling contact fatigue of rolling element bearings is a statistical phenomenon that is strongly affected by the heterogeneous nature of the material microstructure. Heterogeneity in the microstructure is accompanied by randomly distributed weak[...]

Nick Weinzapfel, Auteur ; Farshid Sadeghi, Auteur ; Vasilios Bakolas, Auteur |The continuum theory of elasticity and/or homogeneously discretized finite element models have been commonly used to investigate and analyze subsurface stresses in Hertzian contacts. These approaches, however, do not effectively capture the infl[...]

Ankur Ashtekar, Auteur ; Farshid Sadeghi, Auteur |In this investigation, a new approach was developed to study the influence of cage flexibility on the dynamics of inner and outer races and balls in a bearing. A 3D explicit finite element model (EFEM) of the cage was developed and combined with[...]

Ankur Ashtekar, Auteur ; Farshid Sadeghi, Auteur ; Lars-Erik Stacke, Auteur |A dynamic model for deep groove and angular contact ball bearings was developed to investigate the influence of race defects on the motions of bearing components (i.e., inner and outer races, cage, and balls). In order to determine the effects o[...]

Nihar Raje, Auteur ; Farshid Sadeghi, Auteur ; Richard G. Rateick, Auteur |Fatigue lives of rolling element bearings exhibit a wide scatter due to the statistical nature of the mechanisms responsible for the bearing failure process. Life models that account for this dispersion are empirical in nature and do not provide[...]

Neelesh Deolalikar, Auteur ; Farshid Sadeghi, Auteur ; Sean Marble, Auteur |Highly loaded ball and rolling element bearings are often required to operate in the mixed elastohydrodynamic lubrication regime in which surface asperity contact occurs simultaneously during the lubrication process. Predicting performance (i.e.[...]

Nihar Raje, Auteur ; Farshid Sadeghi, Auteur ; Richard G. Rateick, Auteur |Fatigue lives of rolling element bearings exhibit a wide scatter due to the statistical nature of the rolling contact fatigue failure process. Empirical life models that account for this dispersion do not provide insights into the physical mecha[...]

Behrooz Jalalahmadi, Auteur ; Farshid Sadeghi, Auteur |It has been widely accepted that the microstructure of bearing materials can significantly affect their rolling contact fatigue (RCF) lives. Hence, microlevel topological features of materials will be of significant importance to RCF investigati[...]
