Week 3 Verification of Weld Joints

Objective:- To simulate three different types of welding using three different types of welding materials

Case 1:- stainless steel: the material of the plates must also be the same. Use stainless steel for both weldments and Plates.

Case 2:- Aluminum alloy:- The material chosen for this case is Aluminum alloy ( high strength, wrought ), [ Plate material to be used is stainless steel ]

Case 3:- Bronze:- In order to simulate brazing, you should be using the bronze as the weld material, Assign stainless steel to both the plates, and copper to the ribs.

Procedure:-

Open the static structural analysis system in the Project_Schematic, and rename it to Weld's joints. The material used for this analysis is stainless steel, aluminum alloy, Copper, and bronze. These materials are added to the library in the Engineering Data.

Now proceed to Import the geometry, and verify the geometry is proper, and Update and open the mechanical module.

Equivalent Stress 341 356.71 351.93

Equivalent Elastic strain 0.0018731 0.0034522 0.003202

Equivalent Elastic strain ( Ribs ) 0.00038528 0.00075148 0.00055496

Conclusion:-

Thus, given three types of weld joints are simulated using three different materials.
