Abstract
Process design is one of the most important fields in metal forming, w here the finite element method has appeared to be a useful method for industrial applications. In this study, a program using the rigid-plas tic finite-element method has been developed for process design in thr ee-dimensional plastic deformation. The dies in the computation consis t of four-node patches, and an area-comparison scheme is adopted to de cide the contact condition between the die and the workpiece. Surface integration for the calculation of the friction between the die and th e workpiece has been implemented with care in the numerical treatment. The developed program is applied to a precision-coining process to de termine the amount of piercing. (C) 1997 Elsevier Science S.A.
