Optimum blank design in sheet metal forming by the deformation path iteration method
The authors propose a new optimal blank design in sheet metal forming. The method consists of two stages: the initial blank design, and shape optimization. The first stage is based on ideal forming theory, whereas the second stage implements the deformation path iteration method combined with the rigid-plastic finite element method for sheet metal forming. Numerical results are discussed.
