stresses and central displacement of bearing rings. The numerical model is developed as shown in Fig. 2. The material used in this study is GCr15 steel, and the main parameters are: elastic modulus E= 2.10×105 MPa, Poisson ratio ν=0.3, material density ρ′= 7.85×103 kg/m3, and friction coefficient between steel balls and raceways of bearing rings is 0.15. The bearing ring is meshed with 20-noded......
