This paper presents the prediction of fatigue life and crack propagation in the railway wheel due to the stress field caused by mechanical loads and press fitting process of a railway wheel. A 3-D nonlinear stress analysis model has been applied to estimate stress fields of the railway wheel in press fitting process. Finite element analysis model is presented applying the elastic–plastic fin...
