On One Analysis of Axisymmetric Extrusion by the Use of Flow Lines

Abstract

On the assumption that the flow lines of material might be approximated by the function of hyperbolic tangent an analytical method to examine the mechanics of material during forward extrusion is presented in this paper. For the application of this method to actual extrusion, the unknown quantity is readily determined with the use of material constant obtained through the compression test. Therefore, the mechanics of material during forward extrusion can be obtained approximately without a preliminary extrusion test.
