Summary

The underlying motivation for this work was to test the conventional wisdom that 100 % coverage by shot peening is required to achieve full benefit in terms of compressive residual stress magnitude and depth as well as fatigue strength.

Residual stress-depth distributions were determined for specimens peened to various coverage levels. Fatigue performance was tested at R > 0, so that the shot peened surface was loaded only in tension. Additionally, cold work-depth distributions and the effects of thermal relaxation on both residual stresses and cold work were determined.
