| 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). | ||
