Calculation of the Plastic Metal Flow in the Cold Extrusion Technology by Finite Volume Method

This paper presents an application of the finite volume method to ideal plastic metal flow in extrusion technology. Governing equations for the mass and momentum balance are used in an integral form. Solution domains in the cases considered are discretized with a Cartesian numerical mesh with comput...
