Understanding the fatigue crack growth phenomenon in railheads requires a study of driving forces, such as the crack tip opening and sliding displacements, under repeated rolling contact. Finite element simulations, allowing elastic-plastic deformation, and mixed-mode crack growth laws were utilized
Rolling contact fatigue (RCF) failure is a permanent and quite severe problem and hence of major concern to the modern railway industry. The selection of rail material should be based on a well-founded understanding of RCF. An analysis of the chemical composition, mechanical performance and microstr
