Severe plastic deformation (SPD) is divided to a number of branches. One of the most important branches of SPD of tube materials is parallel tubular channel angular pressing (PTCAP). The PTCAP process is more complicated than another SPD process for metal tubes. The PTCAP process includes two half cycles for obtaining the desired product. There are some factors, which affect the PTCAP process. For instance, deformation ratio, clamping force, channel angles, and curvature angles. In this paper, the PTCAP process for aluminum alloy (Al 5083) was simulated through the finite element ABAQUS software in order to investigate the effect of die parameters. Thus, the influences of deformation ratio, channel angles, and curvature angles on the PTCAP process were examined numerically. In addition, to verify the finite element method (FEM) results, the PTCAP process was done experimentally. To some extent, good conformity was observed between the FEM calculations and experimental results.
