| Abstract: | To explain the phenomenon of residual stress relaxation in high temperature in a certain aero-engine's turbine blade after Laser Shock Processing(LSP),this paper analyzes the mechanism of residual stress relaxation.Then a model for the prediction of residual stress relaxation affected by temperature is established based on grey theory.The calculated results by means of the model are in good agreement with the experimental ones,which prove the feasibility of this method. |
