Item type:Article, Access status: Open Access , Numerical analysis of the influence of lubrication conditions on the filling pattern in a complex process of extruding particular high-melting materials(2012) Krawiec, Agnieszka; Chyła, Paweł; Chyła, Piotr; Bednarek, Sylwia; Łukaszek-Sołek, AnetaIn this paper, the process of extrusion was analyzed numerically for a axisymmetric forging model where there is a complex material flow diagram (Fig. 1a). The analysis was performed assuming a different stoke slenderness ratio so you can control how to fill the die impression (direct extrusion, in direct and side - Fig. 1b)-d), using lubricants with different values of friction factor.
