| Abstract: | This paper describes the flow behaviour of the combined forwardbackward extrusion for axisymmetric seation. An upper bound technique based on the kinematically admissible velocity field is used to determine the extrusion load and power. The theoretical results are compared with know experimental and theoretical data and are found to be in good agreement. |
