EXPERIMENTAL RESEARCH ON FLEXURE DISTORTION AND STRESS IN RAILROAD SUPERSTRUCTURE

Experimental research on flexure, distortion and stress in railroad track structures is described herein. Report undertaken with object of comparing the effect on track of several types of high-speed locomotives for passenger trains. The improved photographic method used to record movements of selected points in different parts of the superstructure makes it possible to measure both flexure distortion and stress at these points with great precision, while avoiding certain shortcomings found in other familiar methods. The data presented in this report was developed prior to 1936 and is offered in a historical context only. Portions of this document are not fully legible.
