Abstract

The subject of this paper is an analysis of metal extrusion processes by the boundary element method (BEM). It is demonstrated here that the BEM can be used to analyze, efficiently and accurately, this complicated class of problems including both material and geometrical nonlinearities. Numerical results for sample problems of plane extrusion of aluminum bars, obtained by the BEM, are presented and discussed in this paper. The BEM results are compared against FEM results for the same sample problems. The FEM results were reported by the authors in a previous publication.
