Week 9 Tension and Torsion test challenge
Objective:- To perform the tension and torsion test on the given specimen for the following cases.
- Testion Test: Displace one end of the specimen to 18mm while keeping the other fixed.
- Tortion Test: Displace one end of the specimen to an angle of 1200 deg.
Find the total deformation, Equivalent stress and Temprature.
Procedure:-
For Tenstion Test:
1. Import the model into Explicit Dynamics analysis on Ansys workbench and rename the geometry accordingly.
2. For meshing patch conforming method was used to the whole body with method as Tetrahedrons. Face sizing was given to the two end faces using sphere of influence type with element size of 2mm and sphere radius of 22mm.
3. For the Tensile test the Model is given Fixed support at one end and Displacement at the other. Displacement of 18mm was given.
4. The temperature for the simulation is obtained by user Defined expression which can be obtained from the worksheet.
For Torsion Test:
1. For the rotation of the model along with the displacement we have to create a Cylinderical system coordinate as mentioned below.
2. Then we refine the middle portion of the model in such a way that the Tortion analysis will be observed with accurate result within the software limits. An element size of 1.5mm and sphere of influence with sphere radius as 8mm and element size of 1mm.
3. Displacement was given along the Y-direction of 1200 deg.
4. Reset of the steps are same of the Tension Test.
Results:-
Tension Test:
Equivalent stress:
Total Deformation:
Temperature:
For Torsion Test:-
Total Deformation:
Equivalent strain:
Temperature:
Equivalent stress:
Conclusion:-
We have performed the tension test and torsion test successfully on steel 1006 specimen, and the stress, strain, and temperature values are listed in the table.
In the tension test, we have observed the Necking so we can conlcude that the specimen is made up of ductile material.
