OBJECTIVE:
Sheet metal bending is to be performed for 3 different materials mentioned below. Variation of certain settings is also to be performed and your conclusions are to be added to the report
Note: Please read the instructions carefully
Run the analysis for the material :
Case 1:Aluminium Alloy 1199( mentioned in the course video),Copper Alloy NL and Magnesium Alloy NL. Find out the Equivalent stress, Equivalent elastic strain and Total Deformation in Y direction and compare the results for the three materials.
Case 2: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.
Case 3: 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
Case1:
Connections:
Meshing:
Analysis setup:
Results:
Directional deformation:
Equivalent Elastic strain:
Equivalent stress:
Directional deformation of sheet:
Eqivalent stress in sheet:
Equivalent strain in sheet:
Now change the sheet material as copper alloy then run the simulation:
Results:

change the sheet material as magnesium alloy and run the analysis:
Case2:
for this case same as sheet material is alluminium alloy change the friction coefficient is 0.19 and run the analysis
Results:
Directional deformation:
Equivalent Elastic strain:
Equivalent stress:
Directional deformation of sheet:

Equivalent stress of sheet:
Case3:
For this case refine the mesh on the plate run the simulation
Results:
