Development of a Granular Cohesive Model for Rolling Contact Fatigue Analysis - Investigations on Material Modeling

Despite the great number of models developed to predict Rolling Contact Fatigue (RCF) [1], understanding RCF failure mechanism remains a significant challenge. This difficulty results from the complexity and the variety of the RCF manifestations and mechanisms [2]. The influence of material microstructure is very significant in RCF mechanisms; nevertheless, today few models at the microscale level exist. Sadeghi and co-workers have developed various models with a microstructure representation: ([3] for example); Alley [4] has investigated a model with crystal plasticity.
