“…These contact characteristics lead to strong plastic deformations of the rail surface and often form the initiation point of roll cycle fatigue (RCF) related crack-like defects such as headchecks and squats. [9,10] In general, rail steels are tested regarding their RCF behavior, for instance, through two-disk roller tests. [11,12] These tests can rank materials by their crack formation tendency but cannot provide information about the local fracture properties of the strongly plastically deformed surface layers.…”

High-pressure torsion (HPT) has been used for investigating the influence of predeformation on the fracture toughness of a fully pearlitic rail steel. The use of HPT enables one to investigate changes in fracture toughness as a function of predeformation over a wide range of strain while simultaneously studying the influence of the crack plane orientation on the fracture toughness. With increasing prestrain, besides a strong increase in hardness, a pronounced anisotropy in the fracture toughness was found. Both the increase in hardness and the anisotropic fracture behavior can be attributed to the shear deformation process leading to an anisotropic composite structure on the nanometer scale.

“…On this scale, sub-modelling approach is often employed to assess the crack initiation on the surfaces of rail and wheel (Liu et al, 2006, Ringsberg et al, 2000, Guagliano and Pau, 2008.…”

“…For example, in predicting fatigue life of rails and wheels (Desimone et al, 2006, Ekberg et al, 2002, simple engineering formulas are commonly utilized together with Multibody system(MBS) analysis. However, due to the assumption of rigid components and elastic material behaviour in MBS simulation, a continuum approach, Finite element method(FEM) cooperating with advanced fatigue life models (Liu et al, 2006, Ringsberg et al, 2000, Sraml et al, 2003 is often employed to do crack initiation/propagation analysis because of its striking versatility. In FEM analysis, material behaviour can be described by sophisticated elasto-plastic models.…”

“…This phenomenon arises primarily where there are contacts with low relative sliding, such as on the rail head on straight tracks. A simulation of a so-called ratcheting model using finite elements carried out by Ringsberg et al [1] identified asymptotic values of the friction coefficient at which crack initiation would occur. In northern Sweden, 60% of rail replacements were found to be due to problems caused by rolling contact fatigue and surface defects, while only 5% were due to flange wear [2].…”

The rail wheel interaction is one of the important mechanics for the study in Railway Engineering, requiring both vast application expertise and dependable analysis approaches. The contact area and pressure distribution in a wheel/rail contact is essential information required in any fatigue or wear calculation and to determine design life, regrinding and maintenance scheme. The objective of this project is to understand, formulate and simulate wheel-rail interaction analysis at static conditions with a view to optimize the wheel and to optimize the mass of the railway wheel subjected to both vehicle load and contact pressures. In railway, engineers applied one of the numerical computation techniques known as Finite Element Analysis (FEA) into Rail-Wheel contact problems to validate their results by comparing them to their real life data obtained over the years. So we have used software ANSYS in this research for Finite analysis of rail wheel interaction
