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
