Abstract
Conventional finite-element methods (FEM) used in metal forming processes usually use the stiffness matrix approach. In this paper, a somewhat unconventional FEM program, which involves the modification of a dynamic finite-element program, is used to solve static metal forming problems. The modification is by adding artificial damping terms to a dynamic program DEFEL, which makes the approach equivalent to Dynamic Relaxation (DR) method. The basic dynamic program DEFEL is first described. Then the theory and equations of DR as applied to DEFEL are presented. Example problems of simple upsetting of solid cylinder, ring compression and deep indentation are included. Results are compared with those available from other sources. In addition, impact on a solid cylinder is calculated by the same program, showing that both dynamic and static solutions can be obtained with one computer program.
