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.
