Finite Element Analysis of Residual Stress in Shot Peening of GH4169 Superalloy
A random multiple shot peening finite element model of nickel-based superalloy GH4169 was established using ABAQUS/Python secondary development technology.Based on this model,the influence of different diameter and velocity of little balls on the residual stress distribution after shot peening was analyzed by finite element simulation.At the same time,the corresponding shot peening process was tested and compared with the FEM results.It can be seen that the magnitude and variation trend of the residual stress simulation results are consistent with the measured values.
