STRESSES IN RAIL HEADS--COMPARISON BETWEEN THEORY AND EXPERIENCE

J Eisenmann

Open publisher page 0 citations

Abstract

This article describes the latest investigations into the problems of rail loading and stresses. Laboratory experiments with a plastic model of a rail are described, with the results charted. These are related to the tests and experience of the German Railways in their investigations of rail failures and damage. Charts are included which show the relations of the shearing stresses in the rail head to the wheel diameter and axle loading, the stresses increasing as the wheel diameter decreases or as the axle load increases.
