Abstract

This work presents a three‐dimensional rigid plastic finite element formulation. The workpiece is discretized with eight node hexahedral isoparametric elements. Friction is included in the formulation by means of a shear stress depending on the relative velocity between the workpiece and the tool. Special attention is given to the contact problems, and a three‐dimensional contact algorithm based on a discretization of the tool surface with triangular elements is presented.

Finally, some selected examples are solved, in order to show the capabilities of the formulation.

A fully three-dimensional elastic-plastic finite-element program for the study of metalforming operations is described. Several applications are discussed, and the finite-element (FE) predictions of metal flow, strain rate and temperature distributions, and the sites of initiation of ductile fractur
