Original abstract

A computational model of fatigue behaviour of two-dimensional (2D) primary crack situated in a railway wheel (RW) rim was designed. The RW rim was placed on the wheel disc of RW with interference fit. Crack behaviour was analysed in the case of rectilinear ride of a train under rolling contact fatigue (RCF). A direction of crack propagation was predicted using Richard criterion. In this way a relationship between stress intensity factors and crack geometry was obtained. The equivalent cyclic stress intensity is calculated and used in a modified Paris equation to predict the crack propagation rate
