Instable Material Flow in Extrusion and Upsetting

CIRP Annals, 1982
In spite of precisely controled tooling the shape and dimensions of extruded cans sometimes vary considerably during production. This phenomenon happens in all forming operations which include an upsetting process such as upsetting, heading, flattening, backward can extrusion etc. Further, experiments brought up the evidence of an instable shift of the
