Abstract: The aim was to analyse distribution rule of residual stress fields in a TC6 titanium
alloy blade with multiple impacts and different spot overlapping ratios by comparing the
numerical simulation and laser shock processing (LSP) experiments results. A dynamic model
based on the finite element method was presented to simulate multiple impacts and different
spot overlapping ratios by single sided LSP with round laser spot, and the distribution rule of
residual stress fields based on different process condition was described. Further, LSP
experiments of multiple impacts and different spot overlapping ratios were executed to compare
the simulation results by measuring and fractographic observation. The results indicated that
simulated values were reasonable with experimental values, and the compressive residual
stresses were greatly increased and driven deeper below the blade surface with multiple impacts
and high spot overlapping ratios on the same spot. © 2013 Institute of Materials, Minerals and
