Week 3 Sheet metal Bending challenge

Objective:

To perform Sheet metal bending to the given model for 3 different materials.

Procedure:

• First import the given Sheet metal bending model.
• Start to provide the boundary conditions.
• Select frictional contacts for both the,
  • Punch to sheet.
  • Sheet to die.
• Start to mesh the model as given meshing parameters.
• Make the no. of steps as 10.
• ON the auto time stepping.
• Solver type to be direct.
• Weak sprigs ON.
• Non-linear control - stabilization constant.
• Select displacement1,2,3
  • X-0-0
  • Y-0,-0.5,-1.5,-3,-6,-9,-12,-13.5,-12,-9,-8.
  • Z-0-0
• Solve the model.
• Do the same procedure for Aluminium alloy [1199], Copper alloy, Magnesium alloy.

Conclusion:

All the simulations were done and model saved.

CASE i:

• Change the material as the same procedure for Aluminium alloy [1199], Copper alloy, Magnesium alloy and continue the procedure.
• Record the stress , strain, and total deformation values.

CASE ii:

• With the material as Aluminium Alloy, change the friction coefficient to 0.19 and run the analysis as mentioned in Case 1.
• Compare the results with that in case 1.
• Record the values for stress, strain, total deformation values.

CASE iii:

• Refine the mesh on the plate such that it doesn't cross the academic limit.
• With Aluminium alloy as material, run the analysis as in Case 1 and compare the results.
• Now plot the values.
