Week 3 Verification of Weld Joints

Aim: To perform Analysis on weld joints and comeout withe the best possible output.

Objectives:

• To apply different materials with prescribed parameters
• Analyze different factors.
• Verify the stress factor.
• Compare all the 3 cases.

Procedure:

Import the model into tyhe Mechanical module.

• Click on geometry tree and rename the other components based on thire structure.
• Click on contacts and select rename based on definition.
• Change the contacts other than welding joints and change their type to frictional and give the frictional coefficient as 0.3

• Mesh the given specimen with a sizing of 7mm selecting the both plates.Click on generate mesh.

• Create the support as fixed and select the geometry as the holes on the base plate.

Create the force on the rectangular hole and define it by component with a magnitude of 15000N.

Insert thye Parameters in the solution Directional deformation in Y axis, Equivalent Stress(Select weld joint geomtries),Equivalent Strain, Safety factor,Contact Tool(Only Frictional joints).

These all are the parameters we are looking for,

CASE-1 Stainless Steel:

Assign stainless stell for all the geometries.

Directional Deformation:

Equivalent Strain:

Equivalent Stress for Weld Joints:

Safety Factor:

CASE-2(Aluminium Alloy):

Directional Deformation:

Equivalent Strain:

Equivalent Stress for Weld joints:

Safety Factor:

CASE-3 (Bronze):

Total Deformation:

Equivalent Strain:

Equivalent Stress for Weld Joints:

Safety Factor:

Comparison:

Materials	Directional Deformation-Y (mm)	Eq. Stress at Weld (Mpa)	Eq. Strain
Stainless Steel	Max:0.35134	Max:302.42	Max:0.000659
Aluminium Alloy	Max:0.4525	Max:264.38	Max:0.000923
Bronze,Cast	Max: 0.40625	Max:265.33	Max:0.000717

Here in all the cases these 2 weld joints experienced the maximum stress compared to the other.
