Abstract

A new calculation method of assessing the rail residual lifetime is proposed. The method is based on the kinetic equation of fatigue crack growth obtained on the basis of the energy approach of the materials fracture mechanics. The proposed calculation method can be used when developing the methods for assessing the rails inspection periodicity.
