Week 3 Verification of Weld Joints

Objective: To simulate three different types of welding using the following materials:

1. Case 1:
   1. Weldments: Stainless steel, 316, annealed
   2. Plates: Stainless steel, 316, annealed
   3. Ribs: Stainless steel, 316, annealed
2. Case 2:
   1. Weldments: Aluminum alloy, high strength, wrought
   2. Plates: Stainless steel, 316, annealed
   3. Ribs: Stainless steel, 316, annealed
3. Case 3:
   1. Weldments: Bronze, cast
   2. Plates: Stainless steel, 316, annealed
   3. Ribs: Copper, C10100, hard

Procedure:

1. Non Weld Contacts:
2. Meshing (Plates Mesh Size 7 mm):
3. Boundary Conditions:

Analysis:

1. Case 1:
   1. Directional Deformation:
   2. Equivalent Elastic Strain:
   3. Equivalent Stress:
2. Case 2:
   1. Directional Deformation:
   2. Equivalent Elastic Strain:
   3. Equivalent Stress:
3. Case 3:
   1. Directional Deformation:
   2. Equivalent Elastic Strain:
   3. Equivalent Stress:

Result:

Cases	Directional Deformation (mm)		Equivalent Elastic Strain (mm/mm)		Equivalent Stress (MPa)
	Maximum	Minimum	Maximum	Minimum	Maximum	Minimum
Case 1	0.38483	-2.5024	0.017164	1.0378×10^-5	2275.3	5.9458
Case 2	0.40171	-2.5887	0.024555	1.0493×10^-5	1799.5	3.5051
Case 3	0.36842	-2.744	0.023181	1.168×10^-5	1846.3	4.9143

Conclusion: The same weld joint experiences the maximum stress in all three cases (indicated by maximum probe). The stress is maximum for case 1, lesser for case 3 and least for case 2. The deformation is maximum for case 2, lesser for case 1 and least for case 3. The strain is maximum for case 2, lesser for case 3 and least for case 1.
