In this work the influence of considering wheel-rail contact creepages on fatigue crack growth rates due to Rolling Contact Fatigue (RCF) is studied. For purpose, FASTSIM algorithm, which considers moving complex pressure distribution with slipping and adhesion zones patch, has been implemented in Abaqus using FORTRAN code subroutines. The developed methodology validated a 60E1 rail profile mod...

In this paper, an analytical model based on Modified Slab Method is presented for rolling of clad sheet or double-layers in which the two layers are bounded prior to rolling. This model considers the general case of asymmetrical rolling due to unequal &#10surface speed, different contact friction, roll diameters, flow stress, and thickness ratios of the two layers. Using this model, rolling par...
