Engineering foundation: Manual on endurance of metals under repeated stress

In 1919, National Research Council, University of Illinois, and Engineering Foundation joined forces for a new attack upon the old problem commonly known as Fatigue of Metals. The Council appointed an advisory committee; the University provided the director, staff and facilities for the research, and the Foundation supplied a substantial fund to pay for special equipment. A number of industries cooperated by contributing funds, materials and information. While this investigation has been progressing, several others have been conducted by Government bureaus and by industries, with little, if any, wasteful duplication. Large additions have been made to knowledge of this subject, but the reports were scattered in numerous scientific and engineering publications, and some results have not been printed. There were requests, therefore, to have the information collected, condensed and put into a form convenient for use by engineers.
