Abstract
The aim of the present work is to study the effect of laser shock peening (LSP) on fatigue life of aluminum alloy (3003-H18) by using different (LSP), single spot, 2-spots with 50% overlap and 3-spots 100% full overlap on the surface to be treated. The effect of laser shock peening (LSP) on the fatigue life were investigated with constant amplitude stress at stress ratio R=-1 at room temperature. The results showed that the fatigue life increment over the life of samples without (LSP) in range (12%) for 1-spot LSP, (18%) for 2-spors LSP and (77%) for 3-spots LSP for aluminum alloy 3003-H18 at 100MPa amplitude stress. Also the results show that the highest fatigue strength was for samples with 3-spots LSP.
