EFFECT OF RESIDUAL STRESSES IN HARDENED RAILS ON THE FORMATION AND PROPAGATION OF STRESS FISSURES DUE TO CYCLIC STRAINS

VLIJANIE OSTATOCNYH NAPRJAZENIJ V ZAKALENNYH REL'SAH VOZNIKNOVENIE I RASPROSTRANENIE USTALOSTNYH TRESCIN PRI CIKLICESKOM IZGIBE

The authors have reached the following conclusions: The railhead, as a result of heat treatment or cold straightening, can develop a considerable drop in the stress limit, a drop in the number of cycles completed before stress fissures occur, a drop in the number of cycles completed during the stress fissure propagation period, a reduction in the critical size of each stress fissure, or a drop in the curability of hardened rail, 2) the residual compression stresses which occur in the rail head accentuate the above characteristics.
