Abstract:  
With the need for more efficient use of metals, consideration of mechanical prestressing during the design phase seems obvious, for the vast majority of fractures are caused by metal fatigue. Reduced weight and increased stress and speed require higher fatigue strength to prevent fracture. Since the primary effect of mechanical prestressing is to increase fatigue strength, the many methods of mechanical prestressing should be considered for highly stressed parts subject to fatigue failure. This technical report, to the best knowledge of the Surface Rolling Committee, is the first publication, except for those on shot peening, devoted solely to mechanical prestressing. Shot peening has been covered extensively in other publications, but surface rolling and other methods for mechanical prestressing have been treated only in scattered articles. Many of these articles are listed in the references for further study.
