FE Simulation of Roll-extrusion Process of Shaped Steel Tube

A FE analysis is conducted to non-mandrel roll extrusion process of formation of square shaped steel tube by means of the non-linear FE analysis software, MSC. Marc, resulting in the identification of distributions of the stress and deformation during the formation process and the structural profile of the shaped tube after formation. The result of the said FE analysis is verified by relevant experiment, providing a positive basis for production of the said shaped tube.
