Week 3 Verification of Weld Joints

Objective:-

     To perform static structural analysis on welding joints using three different materials and to compare the results like directional deformation, stress generated on welded joints and strain developed.  

 Geometry:

 The given geometry was imported.

Weld materials:

    Stainless steel-

Aluminium Alloy;

 Meshing:

Mesh size of 7mm is done for big and small plate.

Fixed support & force:-

15000N Force for rectangular hole which is in small plate applied and circular hole which is in big plate fixed.

Contact:-

 Frictional contacts between big plate to small plate, big plate to rib 1, big plate to rib 2, small plate to rib 1 and small plate to rib 2 were created with friction value of 0.2.

Case 1: Stainless steel used for every connection and plate and ribs.

Directional Deformation:

Equivalent strain:

Equivalent stress for weld joints:

Case 2:- Aluminium alloy used for every connection and plate and ribs.

Directional Deformation:

 

Equivalent strain:-

Equivalent stress for weld joint:-

 Conclusion:-

1. Directional deformation is highest in aluminium compared to other cases.

2. Equivalent strain is highest in the case 2 where the aluminium alloy is used as weldments.

3. Equivalent stress is highest in the case 1 where strainless steel used as a weldments.

 Here we compared the results of all the two cases with pictoral presentation.

Stainless steel is the most aptable material to do welding work with stainless.
