Tension and Torsion test on Steel Specimen

AIM :

To perform Tension and Torsion test on a Steel Specimen and find out Equivalent Stress, total deformation and Temperature.

Model :

Material Selection and their Properties :

1) Steel 1006

A] Tension Test -

Procedure :

• Drag and drop explicit analysis on workspace. In engineering data select the specified materials. In this case, Steel 1006 is selected as materials.
• Open Spaceclaim and import the geometry. Check for any errors and if none are there Close the Spaceclaim.
• Open Mechanical Solver and rename the specimen and apply Steel 1006 as the material.
• Create Coordinate systems on both the ends.

• Mesh the model approriately.

• In analysis settings, let the end time step be 1e-03 and apply fixed support to one end and displacement of 18 mm on other end.
• Now for results, apply equivalent stress,Total deformation and Temperature.

1) Total Deformation -

2) Equivalent Stress -

3) Temperature -

Conclusion -

• As from the above table we can see that the temperature and Stress generated is maximum in Torsion test because of twisting of the specimen.
• In both cases,the stress and temperature generated is maximum at the centre of the specimen.
• In tension test, the fracture is not happened for the given displacement yet.i.e 18 mm.
• In Torsion test, the fracture is occured for the given displacement i.e 1200 degree.
