The researches, connected with the clarification of the influence of the corrosion over the stress and the capability of carrying weight are a key-factor for the correct evaluation of the state of the elements.
All the rails are practically subjected to the influence of the atmosphere, so all of them are under the effects of the atmospheric corrosion, which can have three different aspects – reduction of the geometrical characteristic of the section appearance of surface defects (structural changes) and decrease of the mechanical properties.
In this study, we present a theoretically calculated module to determine the factual borders of the stress and the possibility of carrying weight of a rail track with corrosion (type “continuous beam”).
Dependencies are derived and computational algorithms with calculations and numerical realisation as well.
