Week 9 Tension and Torsion test challenge

Aim:- To Perform tension and torsion test on the specimen.

Tension test:-

To Perform a tension test on the specimen by displacing one end of the specimen to 18mm, while keeping the other fixed and find the total deformation, equivalent stress, and temperature of the specimen.

Procedure:-

1. Import the geometry as given in the challenge.

                                                        Fig 1.Given specimen

2. Add material steel 1006 from explicit materials in engineering data.

                                                                 Fig 2.STEEL 1006 Material 

3. Assign the material STEEL 1006 to the specimen.

4. Create co-ordinate systems on either side of the specimen.

                                            Fig 3. Coordinate systems created on either side of the specimen.

5. Apply Tetrahedron mesh to the specimen using the Automatic method.

6. use Face sizing and type sphere of Influence to mesh both the sides of the specimen with a sphere radius of 22 mm and element size of 3 mm.

                               Fig 4. Sphere of Influence was used to mesh both the sides of the specimen.

7. In Analysis settings, set the end time as 1*10^-3 sec.

8. Insert the Displacement load to the right side of the specimen with a magnitude of 18mm.

                                               Fig 5. displacement load is given to the right  side of the specimen.

9. Give Fixed support to left side of the specimen.

                                                    Fig 6.Fixed support is given to the left side of the specimen.

Torsion test:-

To Perform a torsion test on the specimen, by displacing one end of the specimen to an angle of 1200 degree, and find out the total deformation, equivalent stress, and temperature of the specimen.

Procedure:-

1. Import the geometry as given in the challenge.

2. Assign the material STEEL 1006 to the material.

3. Create a cylindrical co-ordinate system at the middle part of the specimen.

                             Fig 10.Cylindrical co-ordinate system created at the middle part of the specimen.

4. Follow the same procedure as above to create co-ordinate system and to mesh the specimen.

5. Insert Face sizing to mesh the curved surfaces with an element size of 1.5mm.

6. Insert Face sizing to mesh the middle part of the specimen using a sphere of Influence with sphere of radius 8mm and element size of 1mm.

7.Change the co-ordinate system to cylindrical in middle part of the specimen with z principal axis.

8. In Analysis settings, set end time as 1*10^-3 sec.

9.Give Displacement to one end of the specimen with cylindical co-ordinate system with an angle of 1200

                                              Fig 11.Displacement load is given to the specimen.

10.Give Fixed support to the other end of the specimen.

                                                Fig 12.Fixed support given to the specimen.

Results:-

Total Deformation

                                                               Fig 13.Total Deformation

Equivalent stress

                                                            Fig 14.Equivalent stress

Temperature of the specimen

                                                              Fig 15. Temperature of the specimen.                                               

Conclusion :-

Thus tension test and torsion test on the specimen was performed as given in the challenge, and the results total deformation equivalent stress, Temperature of the specimen were found out.
