Abstract
This paper employs rigid-plastic finite element DEFORM™ 2D software to investigate the plastic deformation behavior of a single rod during its axisymmetric extrusion through a conical die. Under various extrusion conditions, the present numerical analysis investigates the damage factor distributions, the variation of the void dimension at the exit, the deformation mechanisms, and the mean stress distributions around the defective void. The relative influences of the semi-angle of the die, the diameter of the initial void, and the friction factors, respectively, are systematically examined. Additionally, the correlations between the before and after extrusion for defective void and a series of damage factors are explored. The simulation results verify the suitability of the current finite element software for modeling the extrusion of single rods containing internal voids.
