1)Equivalent stress for the whole setup:
Max stress : 3824.5 MPa
2)Equivalent Plastic strain for the workpiece :
Max Plastic strain: 2.5508
3) Directional Deformation in the Z axis for the workpiece:
Max Displacement of the side of the workpiece: 9.7mm
4)Prove that the workpiece has displaced by 90mm :
The tip of the work piece was displaced by 89.6 mm as shown in the figure above.
Inference : The material used for the above simulation was copper nonlinear alloy. A rolling operation was simulated using Ansys workbench. The above simulation showed that the change in dimensions of the workpiece. The sides of the workpiece increased by maximum of 9.7 mm in Z direction.
