FEM Simulation Comparisons of Backward Extrusion
This study with constant shear friction uses DEFORM 2D software to perform FEM simulation of backward extrusion, and compares to SUPERFORM FEM simulation to realize the variations of forming conditions with the punch force and the final cup height. Effects of frictional factor, punch nose face angle, punch nose radius, and punch seizing length on equivalent stress, equivalent strain, velocity field, punch force, and deformed shape can be explored. Meanwhile using both FEM softwares to simulate can realize variations of both models in order to provide the reference of backward extrusion.
