Abstract

Laser Shock Processing (LSP) is a new technique for strengthening the metals. This paper investigates the effects of LSP on the fatigue crack growth (FCG) behavior of 2024-T62 aluminum alloy. The FCG tests results show that the fatigue crack growth rates (FCGRs) at a given stress intensity have been reduced by over one order of magnitude.
