Abstract:
In the present study, the effect of back pressure on the filling fraction of dies during pure shear extrusion, a novel severe plastic deformation process, is investigated by finite element analysis. The applied load predicted by simulation during the pure shear extrusion process is verified and a good agreement between the predicted results at a Coulomb friction factor of 0.12 and experimentsis found. Next, various amounts of back pressure are applied to a plunger at the exit channel of the dies, and their influence on the filling fraction of the die are studied.
