Efficient Shaping or Reshaping of Complex 3D Parts Using Engineered Residual Stress

Abstract: A model was developed for solving the inverse problem of distortion.

  • Significant improvement in overall shape of the validation part was observed.
    • Demonstrated good predictive performance for the inverse problem of reshaping.
  • The extreme distortion in a partially-peened state was predictable.
  • The difference between the predicted final shape and the actual final shape was less than the difference between the actual final shape and the target shape.
    • Demonstrated good predictive performance for the forward problem of reshaping.

 

Originally presented at the Residual Stress Summit 2017 in Dayton, OH.
