Railway rails suffer from rolling contact fatigue damage such as initiation and propagation of surface cracks. The head check crack is one type of surface-initiated crack that occurs in the rail due to successive accumulation of plastic material deformations. Once initiated, the size of the crack is 0.3 to 0.5 mm. The head check crack has recently been emphasised due to large frequency on the gauge corner of the (high) rail at curved track. There are approaches in the literature on fatigue life prediction of head check crack initiation. However, less work can be found on head check crack propagation. The present paper is a literature survey on appoaches and models that can be used to assess the circumstances under which head check cracks grow. The following issues are addressed: multiaxial fatigue crack propagation, prediction of crack growth direction and rate, fluid entrapment and crack face friction, and numerical modelling of crack propagation using the finite element method.
