ANALYSIS OF DIFFERENT MODELING APPROACH AT DETERMINING OF BACKWARD EXTRUSION FORCE ON AlCu5PbBi MATERIAL.

The goal of the paper is to present an outline of different modeling approach at determining of backward extrusion force on AlCu5PbBi material and to compare them with experimental obtained results. Stochastic modeling in the paper is based on the statistic processing of central composite experimental design i.e. in this investigations central composite circumscribed (CCC) design. The numerical modeling is based on the finite element method (FEM) using ABAQUS 6.4.1. Explicit software. [ABSTRACT FROM AUTHOR]
