Development and FEM Modeling of a New Severe Plastic Deformation Process according to the Reverse Shear Scheme

Figure 5

Distribution accumulated plastic strain values for the deformation operations using the RS-60 deformation route: 4 operations, material used is Cu-ETP copper, and friction 0.5 according to Levanov [34]. Workpiece dimensions: width 20 mm, height 18 mm, and length 80 mm. (a) Original position of the workpiece in the die. (b) Intermediate position of the workpiece at the 2nd stage of deformation. (c) Position of the workpiece at the end of the 2nd stage of deformation. (d) Original position of the workpiece at the 3rd stage of deformation. (e) Position of the workpiece at the end of the 3rd stage of deformation. (f) Final position of the workpiece at the 4th stage of deformation.
