| Abstract | Fatigue crack initiation properties of rail-steels were determined experimentally. One new and four used rail steels were investigated. The effects of the following parameters were studied: stress ratio (ratio of minimum to maximum stress in a cycle), control mode, specimen orientation, and periodic overstrain. Both constant and variable strain amplitude experiments were performed. A model was developed, employing an equivalent strain parameter, which allowed prediction of variable amplitude fatigue crack initiation within the basic data variability. |
