The mode I fatigue threshold for head hardened rail steel

Journal Article


Abstract


  • This short communication serves to report the results of fatigue testing which was conducted on single-edge-notched rectangular bar spec mens machined from the head of a length of virgin head-hardened heavy haul railway rail, manufactured using an ingot route. An increasing load technique was employed for threshold determination with small positive stress ratio R. The tests resulted in a fatigue threshold of 11.4 ± 0.4 MPa m1/2 for R = 0.11. This is slightly lower than the established fatigue threshold for standard carbon rail steel of 12-14 MPa m1/2. © 1998 Elsevier Science Ltd.
