Numerical Simulation and Response Optimizer Design of Strengthening Effects Induced by Laser Shock Peening

摘要：

By using 6061-T6 Aluminum alloy plate, the micro-plastic flow process of surface material induced by LSP was analyzed with FEM code ABAQUS/CAE, the change of residual stress distribution and micro-topography was shown dynamically. Based on the results of numerical simulation, Factorial model of MINITAB was used to carry out response optimizer design to gain the optimum strengthening effects. After the creation and analysis of factorial design, contour plots and surface plots were output, the optimum strengthening effects were obtained by statistic results of response optimizer, and the influencing factors of correspondence were achieved. Finally, LSP experiments were carried out with the optimized laser parameters on 6061-T6 plate, good agreement was found between numerical and experiment results.
