INFLUENCE OF CONTACT STATE ON PROPAGATION PATH OF RAIL SURFACE CRACK

In order to investigate the formation mechanism of fishhook shaped spalling defect on rail surface, the fatigue calculation model of wheel/rail rolling contact was established and the prediction method of crack propagation path was proposed based on the contact element method and maximum circumferen...
