“…The fretting contact of a NBSX alloy is a highly nonlinear problem, especially after considering the contact friction. 33 In order to avoid possible numerical divergence, the configuration of the finite element model must be carefully performed. The contact between the specimen and the contact pad is set as finite sliding and surfaceto-surface contact.…”

The fretting fatigue crack formation and propagation behaviors of Ni‐based single‐crystal (NBSX) superalloys are investigated in this paper. Subsurface crack formation process is revealed by in situ fretting fatigue experiment. The crack is observed to form on subsurface area, then propagates to the contact surface. Inclusions in materials are found to have obvious effects on crack propagation, and slip lines are closely related to the crack propagation direction. Crystal plastic finite element method (CPFEM) simulation is used to simulate crack formation position. The accumulative plastic strain peaks at the edge of contact zone and the subsurface area. The results show that the CPFEM simulation and in situ observation achieve good agreements.

“…Most recently, finite element simulation has been employed as a powerful tool in studying fretting fatigue. It has now been established that plastic deformation, damage, and crack formation take place at a scale which is comparable with the grain size. Hence, changes in the microstructure can affect the fretting behaviour so that an accurate numerical simulation of the fretting process will need to be based on a microstructure‐sensitive method.…”

“…Mayeur et al studied the effect of texture and suggested ratcheting as the main cyclic plastic deformation mechanism which is greatly affected by the texture. Other studies on the main plastic deformation mechanism using crystal plasticity simulations have been conducted in the last decade, in which the effect of grain sizes and orientations on the maximum cyclic plastic shear strain was explored, and the results showed that maximum cyclic plastic shear decreases by increasing grain sizes.…”

The onset of fretting fatigue is characterized by material microstructural changes in which the extent of the damage is comparable to grain size, and hence, the microstructure characteristics could have a significant effect on fatigue crack initiation. In this paper, a three‐dimensional finite element crystal plasticity framework is presented for simulation of the fretting fatigue. Controlled Poisson Voronoi tessellation (CPVT) method is employed to generate the polycrystalline region. In the CPVT method, regularity parameter controls the shape of grains. In this study, the impact of grain size and regularity parameter on crack initiation life and initiation site has been investigated. Cumulative plastic slip was used as a parameter of microstructure‐sensitive fatigue indicator. This parameter could effectively predict the location of crack initiation and its life. The results show that regularity parameter has a significant effect on the location of crack initiation. Furthermore, the effect of grain size on the fretting fatigue life of 316L stainless steel was investigated experimentally through testing different specimens with different grain sizes, to validate the simulation results.
