Origin: NASA Research for Eliminating Metal Fatigue

When rapid oscillation of blanket wearing looms at Chatham Manufacturing Company caused significant metal fatigue, the company turned to NC/STRC for a NASA data bank computer search. The search pinpointed tensile stress, and suggested a built-in residual compressive stress as a solution. Shot peening bombarding a part with a high velocity stream of very small shot to pound and compress the part's surface, was found to be the only practical method for creating compressive stress. The method has been successful and the company estimates its annual savings as a quarter million dollars.
