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.

Contacts:-

Frictional contacts are given to the Big plate, Small Plate, and ribs with a Friction coefficient of 0.2.

                                                               Fig 2. Contacts

Meshing:-

Body sizing meshing of 7mm is given to the Big plate and small plate

Fixed support and Load definition:-

                                                    Fig3. Fixed support is given to the holes

                                                        Fig4. The force of 15000 N is given

Conclusion:-

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