Week 3 Verification of Weld Joints

OBJECTIVES:-

To find out directional deformation ,equivalent stress and strain for the welding of stainless steel ,aluminium wrought and bronze
identify highest equivalent stress in each case for weld joint and compare them

PROCEDURE:-

Open the ANSYS WORKBENCH R2
Select static structural analysis
Rename it's name as stainless welding for first case (for second case rename as AL wrought and dor third case rename as brazing )
select engineering data and choose material as stainless steel
import the geometry
Open the ansys Mechanical
in geometry section , rename body parts appropriatly
choose stainless steel as material for all plates ,ribs and weld joints
in connection section, right click on contacts and choose rename all based on defenition
select the contact which are between bigplate and small plate ,rib 1 and big plate ,rib 2 and big plate ,rib 1 and small plate & rib 2 and small plate and choose type as frictional and input coefficient of friction as 0.2
select big palte and small plate by body selecting tool and In mesh section input mesh element size as 5 mm
right click on static structural insert fixed suport and select its scope as sides 5 holes on big plate
insert force and input its scope by selecting 4 sides of rectangle hole on small plate
in solution section insert directional deformation (Select y axis) ,equivalent stress and strain
run solve

RESULT:-

DIRECTIONAL DEFORMATION :

EQUIVALENT STRESS :-

EQUIVALENT STRESS IN WELD JOINTS :-

EQUIVALENT STRAIN :-

2.ALUMINIUM WROUGHT AS WELD MATERIAL .PALTE AND RIBS MATERIALS ARE STAINLESS STEEL:-

DEIRECTIONAL DEFORMATION:-

EQUIVALENT STRAIN :-

EQUIVALENT STRESS :-

3. WELD MATERIAL IS BRONZE , PLATE MATERIAL IS STAINLESS STEEL AND RIBS MATERIAL IS COPPER:-

DIRECTIONAL DEFORMATION :-

EQUIVALENT STRAIN :-

EQVALENT STRESS :-

EQUIVALENT STRESS IN WELD JOINTS :-

TABULATION :-

weld material	DIRECTIONAL DEFORMATION (mm)	EQUIVALENT STRAIN (mm/mm)	EQUIVALENT STRESS (MPa)	EQUIVALENT STRESS IN WELD JOINTS (MPa)
stainless steel	0.34889	0.0020237	361.91	291.23
aluminium wrought	0.36436	0.0034959	367.18	241.15
brazing	0.38798	0.0024888	371.03	267.47

CONCLUSION:-

Directional deformation is minimum for stainless steel weld is 0.34889 mm and deformation maximum for brazing is 0.38798 mm
By comparing equibvalent stress in weld joints it is maximum in stainless welding is 291.23 MPa
equivalent stress is minimum in weld joints is 241.15 MPa and weld material is aluminium wrought
equivalent strain is minimum in stainless steel is .0020237 mm/mm
equivalent strain is maximium in aluminium wrought weld joint
