This work by well‐known authors, Chief of Applied Mechanics Division, Consultant, and Co‐ordination Director respectively of the Battelle Memorial Institute, Columbus, Ohio, has been sponsored by the Bureau of Aeronautics, Department of the Navy, who commissioned Battelle to survey the present state of knowledge. Such a survey must obviously be directed towards some particular objective. In the present case it was desired to summarize most of the information required by designers and engineers who may have some knowledge of, but no extensive practical experience in, fatigue problems.
