Tension and Torsion test

Tension Test

Objective:

Perform the Tension Test by displacing one end of the specimen to 18mm while keeping the other fixed. and find out the total deformation, equivalent stress and temperature of the specimen.

1. Analysis System: Explicit Dynamics
2. Material Properties: Steel 1006 (Explicit Material)

3. Mesh:

Conclusion:

Sr. No	Result Plot	Values
1	Equivalent stress (Mpa)	610.15
2	Total Deformation(mm)	18.004
3	Temperatures(°C)	266.76

• Equivalent stress of 610.15 Mpa is get generated in tension test of specimen
• Total deformation of 18.004 mm is observed while tension test.
• And while deformation of specimen, it is observed that temperature of 266.76 degree Celsius is get generated at neck region of specimen.

Torsion Test

Objective:

Perform the torsion by displacing one end of the specimen to an angle of 1200 degree while keeping the other fixed. and find out the total deformation, equivalent stress and temperature of the specimen.

1. Analysis System: Explicit Dynamics

Conclusion:

Sr. No	Result Plot	Values
1	Equivalent stress (Mpa)	565.71
2	Total Deformation(mm)	13.241
3	Temperatures(°C)	455.52°

• Equivalent stress of 565.71 Mpa is get generated in torsion test of specimen
• Total deformation of 13.241 mm is observed while torsion test.
• And while deformation of specimen, it is observed that maximum temperature of 455.52 °C is get generated in the specimen.

Final conclusion based on the both tests :

• Higher temperature is generated in the specimen during torsion test around 455.52 °C.
• And higher equivalent stress is getting generated in tension test around 610 Mpa.
