Comparing the obtained results for the strain distribution, a large difference can be seen at the bottom and the corner of the punch. In HDD process, the plastic strain distribution is more uniform compared to CDD process and the maximum strain values are lower. Figure 6 : Experimental FLD and numerical results for principal strains distribution after 20 mm of punch displacement. Figure 7 : Thickness distribution in the radial direction after 15 mm of punch displacement.
