BEHAVIOUR OF THE METAL OF RAILS AND WHEELS IN THE CONTACT ZONE. 1. RESIDUAL STRESSES IN RAILS (ADDITIONAL MEASUREMENTS), 2. CHECKING OF THE FATIGUE CRITERION PROPOSED BY MR DANG VAN (ADDITIONAL MEASUREMENTS), 3. RELATIONSHIPS BETWEEN DYNAMIC WHEEL-LOAD AND WHEEL DIAMETER, 4. GENERAL CONCLUSIONS

Parts 1 and 2 of this report give the results of the additional measurements, which confirm the results previously obtained during the study of the residual stress field in rails and also the fatigue criterion proposed in report C 53/RP 7. Part 3 gives the relationship to be taken into account in the choice of permissible dynamic wheel-load as a function of the wheel diameter. Part 4 summarises the respective influences of the principal parameters connected with rail fatigue.
