This paper presents an experimental study on the effect of shot peening on
mechanical properties and residual stresses of 2024-T351 Aluminum alloy. Under the
effects of shot peening time SPT the results show that the existence of SPT can
improve the mechanical properties and fatigue life up to a limit value of SPT. The 15
minutes SPT gave the highest value of (σu, σy) which is about 6.7 % for (σu) and 11.7
% for (σy). Empirical equations were proposed to evaluate the SPT with the
endurance limit stress and the residual stresses.
