Numerical Simulation of Tube Extrusion Process of AISI304 and Comparing with Upper Bound Solutions

The study purpose was to evaluate the effect of initial billet temperature, extrusion speed, extrusion ratio and angle on the tube extrusion process of AISI304, particularly the extrusion force, and achieve optimal parameters. Abaqus software was used for the simulation purpose. 12 samples were evaluated with different initial conditions. Two-dimensional axisymmetric model was used to simulate the process, due to the axial symmetry of the process. Mechanical-thermal coupled solution was used for process solution. Also, CAX4RT elements were used for achieving all the degrees of freedom. The initial temperature was found to have the strongest effect on the force.
