The paper presents semi-analytical approaches to the method of evaluating strain-stress mode of railway rails when a part of the solution is in the form of ramp functions whose rate of change cannot be adequately considered using the standard method of finite elements. The proposed model of a multipoint boundary value problem allows for effective evaluation of the rail’s work against the changing of its profile, i.e. due to its wear.
