- 摘要：Surface cracks in railway networks are generally semi-elliptical. In this paper, crack geometry is placed in a semi- elliptical shape inside the UIC60 rail crown used in railway applications. Also, the stress intensity factors (SIFs) are evaluated by changing the friction between the railway wheel and UIC60 rail and the traction force under the influence of periodic overloads. 3D analysis was performed using finite element method (FEM) to calculate stress history. The UIC 60 rail is used for surface fatigue cracks simulation in rail–wheel wet contact. Also, a boundary element method (BEM)...
