Abstract :
To determine the kinematically admissible velocity field of each extrusion region, we analyzed multi-channel extrusion with rectangular ring based on upper-bound element method. The height of each channel and the upper-bound force of extrusion were carried out by calculation of the upper-bound power. The result of the calculation was verified by experiment data.
