THREE-DIMENSIONAL PHOTOELASTIC INVESTIGATION OF THE PRINCIPAL STRESSES AND MAXIMUM SHEARS IN THE HEAD OF A MODEL OF A RAILROAD RAIL

This report discusses the technique used to make a photoelastic model of a rail which indicates the interior stresses present under load. Differences between frozen patterns and those obtained at room temperature are discussed. The method to determine actual principal stresses and principal shears is also described and discussed.
