Summary
An elastic-plastic three-dimensional finite-element formulation is presented for the study of bulk metalforming problems. The incremental technique is based upon the Prandtl-Reuss flow rule and von Mises’ yield criterion, and incorporates a finite-deformation formulation using correct definitions of stress and strain increment for accurate and efficient solution of large-strain analyses.
The finite-element technique has been used to model a number of metalforming processes: the forging of rectangular blocks and a connecting rod, the rolling of thick steel billets and the plane-strain side pressing of circular and shaped sections. These results illustrate the ability of the technique to predict not only flow patterns and forming loads, but also components of stress and the location of ductile fractures.
