Abstract

The effect of the inflection point of die profile has been investigated for
dies designed according to the streamline concept, dies designed with different
inflection point have been adopted (0.25 , 0.5 , 0.75 ) from the original length of
die, under the axismmetric condition with reduction of area (%40), under
frictionless condition, with pass length (20 mm).A special (F.E.M) cod (Ansys 5.4)
has been applied for analysis.The results in this study shows that the position of
inflection point effectual on extrusion load and the strain distribution, and the
inflection point at which the extrusion load is minimum and more homogenous
strain distribution lies in middle of die (i.e at 0.5 L).
