| Abstract: | Based on the CAD technique of Unigraphics,the geometric data of the complex deep-drawn part are picked up, and an effective method proposed in Ref.1] is used to calculate the initial bank of the deep-drawn part. Adopting the large deformation theory and the assumption of ideal forming, the formula and FE expression of one-step approach are provied, for analyzing the forming process of complex deep-drawn parts. Through several test cases with the main concern on thickness strain distribution, the presented numerical method can save much computational time and obtain satisfactory results. |
