Rise of Fatigue Crack in the Head of the Rail

Tapkov, K. A., Muravev, V. V.

Article language: Russian

Abstract. The process of crack birth and rise in the head of the rail with the train load with CNII-X3 (93 tons) is described. It is founded, that in case if stresses, which fits to the GOST 51685-2013, crack birth happens after operational time of 1846 million tons, and rail become in dangerous defect category after operational time of 1883 million tons. Also, it is found that rise of residual stresses after rail producing decreases rail lifetime for safety usage.

Keywords: math modeling, rail, fatigue crack, residual stresses
