Abstract

We consider a computational model of loading of railroad rails in service under the operating conditions. We analyze main types of cracklike defects initiated in the railheads. On the basis of the energy approach of fracture mechanics, we construct a mathematical model for the evaluation of the period of subcritical growth of normal cracks in railheads. The obtained results of theoretical calculations are in good agreement with the averaged statistical data of scaled-down investigations. [ABSTRACT FROM AUTHOR]
