Summary:
The type of metal flow and stress distribution in the metal extrusion process is highly complex for the complicated die design. In this work, a finite element simulation of Al-1100 rod extrusion was successfully achieved using the commercial finite element code Deform-3D. The results show that the finite element model was successfully simulates the stress distribution in the direct rod extrusion of Al-1100. Besides that, the optimum die angle reduces the magnitude of normal, shear, and effective stresses. We can conclude from this study that maximum stresses occur when the rod is in contact with the die at the exit stage.
