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.

“A screening of existent commercial and non-commercial tools was carried out in respect to their fracture mechanics capabilities, their design abilities, implementation as well as their complexity. Although, there are many software possibilities, only those within the reach of the author were evaluated. This resulted in the selection of the commercial tool StressCheck®. The assessment of crack propagation on compact tension and two stringer specimens governed by the Paris and Forman regimes was satisfactory compared with experimental results using the material data from simple standard specimens.”
