FURTHER THREE-DIMENSIONAL PHOTOELASTIC STUDIES OF STRESSES IN RAIL HEAD DUE TO WHEEL CONTACT PRESSURE

A transparent model of a rail head about two-thirds scale was constructed and tested. The model testing showed that the three principal stresses are compressive immediately under the wheel, but as we go away from the wheel both to the right and to the left, all these compressive stresses become tensile. The main difficulty in this study was not studying the stresses in the model of the rail head or the rail, but rather from the difficulties of interpreting the meaning of the stresses in relation to shelly rail failures, or failures in general.
