| چکیده | ||
| In this paper the eccentric forward extrusion of sections has been simulated and analyzed using FEM Abaqus-explicit. The results have been compared to those obtained from upper bound theorem and experimental works. Close agreements was observed between the FEM and experimental work and as compared with the upper bound data more realistic and better predictions were made by the authors’ method. The sections considered in this work were circular and square shaped cross sections. Process parameters such as die length, friction factor and percentage of eccentricity have been investigated and their influence on the relative extrusion pressure and the curvature of the extruded profiles has been illustrated. The effect of die profile has also been studied and shown that a 10 percent reduction in the extrusion pressure could be achieved by using the optimum die profile. | ||
