| Abstract: | The non-mandrel double-pass roll extrusion process of square shaped tube was simulated using nonlinear FEM software. The distribution and variation of stress and deformation as well as the shape of the tube after forming were obtained. The simulation results were verified by experiments. The study provides a useful base for the propractice |
