The purpose of this work is to evaluate the effect of changing cyclic yield strength levels of either wheels or rails on the plastic strain through FEM analysis. The simulations have been carried out with implicit two-dimensional finite element models both in clean contact conditions and in presence of solid contaminants. The materials used are some of the most traded in Europe and in America, with the addition of SANDLOS®S, an innovative steel designed specifically for sandy environments. FEM results were correlated to worn mass and optical micrographs previously achieved in rolling contact tests performed on small-scale specimens.

Abstract
The purpose of this work is to evaluate the effect of changing cyclic yield strength levels of either wheels or rails on the plastic strain through FEM analysis. The simulations have been carried out with implicit two-dimensional finite element models both in clean contact conditions and in presence of solid contaminants. The materials used are some of the most traded in Europe and in America, with the addition of SANDLOS®S, an innovative steel designed specifically for sandy environments. FEM results were correlated to worn mass and optical micrographs previously achieved in rolling contact tests performed on small-scale specimens.File in questo prodotto:
