E. Halbritter et G. Molnarka, Calculation of the optimal shape of nonconical dies by minimizing necessary forces, ADV EN SOFT, 30(9-11), 1999, pp. 735-740
A mathematical model is given for the metal forming in an axisymmetric nonc
onical converging die. By using the Maple V system a semianalytical algorit
hm is proposed for the calculation of the optimal shape of the die which mi
nimizes the consumed energy of the deformation and the power of the frictio
n forces at the wall. Two examples are presented to demonstrate the efficie
ncy of the proposed method. (C) 1999 Elsevier Science Ltd and Civil-Comp Lt
