Abstract

A comparison of the patterns of development of fatigue cracks in the modeling of the operational loading process and the calculated pattern, according to the linear summation algorithm using the standard fatigue fracture kinetic diagram of the same material, is carried out. The material is the low-alloy steel type 20L. During the tests, the load on a curved railway track section was simulated. The parameters of the original fatigue fracture kinetic diagram of material were corrected to adapt it to the calculation under irregular loading of this type.

Keywords

cast railway parts, cast low-alloy steel, service loading block, secondary fatigue fracture diagram
