Abstract
A method of forming a part that has areas of high strain and predicted areas of low strain from a blank and method of designing a die for forming such a part. Predicted areas of low strain are identified that are adjacent to predicted areas of high strain. A pre-forming die is designed to form the blank to provide a donor pocket in an intermediate part in a predicted low strain area that is adjacent to the predicted high strain area. The donor pocket of the intermediate part is drawn into the predicted high strain area while forming the intermediate part into the part.
