Chateau, Xavier A simplified approach for sheet forming processes design. (English) Zbl 0809.73045 Int. J. Mech. Sci. 36, No. 6, 579-597 (1994). A new approach is developed to improve sheet forming parts and sheet forming processes design. In order to apply classical optimization methods, an energetic criterion is defined. With a geometrical definition of sheet forming processes, it is shown how to use this criterion to find the optimal displacement path between a flat blank and the part shape. Then, the classical assumptions of rigid-plastic behaviour and of thin shell geometry are introduced. This paper concludes with numerical applications of the approach and analysis of formability criterion applications.
