Abstract
Based on theoretical analysis, finite element software ABAQUS and MSC.Fatigue were used to establish the forecasting model of fatigue life for laser shot peening (LSP) process. By using a standard stretch test sample of 6061-T6 aluminium alloy, the residual stress field induced by LSP was analyzed with ABAQUS code firstly, and then the stress field model was imported into MSC.Fatigue code for the crack growth analysis. The residual stress distribution and its effect on crack propagation life induced by LSP are numerical studied, and the fatigue life is predicted. The results show that numerical simulation approach is valuable for analyzing the fatigue crack growth and influence of process parameters on fatigue life.
