Rolling Contact Fatigue (RCF) is the result of crack initiation and propagation leading to surface damages. This study proposes a mesoscopic model for RCF crack initiation simulation. Finite Element Method (FEM) is used to obtain stresses using cubic elasticity. Persistent Slip Bands (PSBs) are modeled using polycrystalline geometry and grain orientations. PSBs can pass through Grain Boundaries (GBs) if the misorientation of the adjacent grains is lower than a critical angle. The Tanaka-Mura micromechanical model is then used to calculate the number of loading cycles required to initiate cracks. The results are compared to previous models and experiments. Initiation depths appear to be consistent.

A numerical model for rolling contact fatigue has been developed using finite element method and the Tanaka-Mura micromechanical model to calculate fatigue crack threshold. Two different approaches are compared: macroscopic modeling and mesoscopic modeling which considers a Voronoi polycrystalline geometry. Smooth and dented surface contacts are considered and different methods for computing shear stress are compared. It is shown that a mesoscopic length scale consideration offers benefits over a macroscopic approach in the case of dented surface meanwhile orthogonal shear stress computation on the macroscopic model can legitimately be used in the case of Hertzian contact. The article also highlights that mesoscopic modeling allows for life scatter on fatigue crack threshold. Initiation depths are consistent with literature experiments.

cited By 0; Mechanical contacts in rolling element bearings and gears are increasingly loaded nowadays. In high temperature applications, surface treatments such as gas-nitriding are used to increase their rolling contact fatigue life. This study focuses on the prediction of the location of crack initiation for gas-nitrided steels subjected to rolling contact fatigue taking into account the material property gradients induced by the nitriding process. Several approaches based on the Dang Van criterion are compared to experimental data to find the most reliable prediction model. © 2019 Elsevier Ltd

International audience; In rolling contact fatigue (RCF), failure mechanisms are known to be very sensitive to material microstructure. Yet, among the different numerical models developed to predict the RCF life, few models use a microstructure representation. A granular cohesive finite element model has been developed to simulate progressive damage of a structure subject to RCF and to investigate failure initiation mechanisms. This paper focuses on the implementation of crystal elasticity in the model. The numerical analysis of a representative volume element (RVE) validates the use of cubic elasticity to represent crystal behavior. The influence of the RVE size and the influence of boundary conditions applied on the RVE are evaluated in the finite element approximation framework. As regards the implementation of cubic elasticity in the RCF model, the generation of stress singularities at triple junctions is first highlighted. Then the average value of the intergranular shear stress is proved to be mesh size independent and therefore can be used as damage criterion. Finally, the influence of crystal elasticity on micro-cracks distribution is presented.

The study of rolling contact fatigue in spur gears requires a good comprehension of all the phenomena occurring at the material scale. On a numerical point of view, a realistic representation of the material and of the load repartition function of the local micro-geometries is needed. However the resulting models are often complex and time-consuming. So, this work aims at developing a model meeting these specificities. Thus, different sections of the spur gear material granular geometry are simulated first. Secondly, the contact pressure fields are computed accurately relatively to the simulated surface microgeometry. Then, the influence of several parameters on their rolling contact fatigue life is highlighted. Among friction, sliding coefficient, load variation and roughness, these individual or combined parameters are taken into account in the model, tested and their impact stressed out. Finally, a fatigue criteria based on rolling contact fatigue micro-cracks nucleation at grain boundaries is proposed in order to compare simulations and influencing parameters to the reference.

Colloque avec actes et comité de lecture. Internationale.; International audience; Les mécanismes d'initiation de fissures en fatigue de contact sont fortement liés à la microstructrure du matériau. Cependant, la plupart des modèles utilisés pour prédire la durée de vie en fatigue de contact se situent à l'échelle macroscopique. Un modèle basé sur une représentation de type Voronoi des grains (échelle mésoscopique) est développé afin d'analyser les mécanismes d'initiation. Le concept d'endommagement est appliqué aux joints de grain modélisés par la méthode des zones cohésives (CZM). La représentativité du modèle a été améliorée par la modélisation de l'anisotropie cristalline. Enfin, une nouvelle méthode d'application de l'endommagement aux joints de grain a permis de rendre les résultats plus cohérents en termes d'estimation de la durée de vie.

In Rolling Contact Fatigue (RCF), understanding initiation and propagation failure mechanisms remains a challenge. A cohesive Finite Element model has been developed to investigate microstructure role on initiation mechanisms. The approach consists in modelling the Grain Boundary (GB) progressive damage (from initial undamaged state to failure). In this paper, numerical singularities at triple junctions are highlighted and cohesive stiffness values (for undamaged and fully damaged GB) are defined. Preliminary results underscore the influence of damage application: a linear relation between cohesive stiffness and damage is not suitable to simulate progressive damage.
