BEHAVIOUR OF THE METAL OF RAILS AND WHEELS IN THE CONTACT ZONE. COMPOSITION OF THE DIFFERENT STRESS CONDITIONS IN THE WHEEL/RAIL CONTACT ZONE. DEVELOPMENT OF A NEW FATIGUE CRITERION

The first very brief part of this report contains some additional results concerning the residual stresses in the rail. The second part, which constitutes the more essential part of the study, deals with calculations on the composition of the residual stresses induced in the rail during the passage of a wheel, for a wheel, for different wheel- loads and diameters, transverse curvature radii of wheel-tyres, rail inertia, and track moduli. Some qualitative conclusions on the influence of these various parameters have been given in using an original fatique criterion, the principles of which are also outlined in this report. This criterion should permit a quantitative analysis of the fatigue phenomena to be made when the results of the fatigue tests in progress are known.
