Week 9 Tension and Torsion test challenge

#9 Week Assignment- Introduction to Ansys Workbench

AIM: To perform the simulation on the given specimen and observe the results of various parameters.

Objectives:

1. Case setup for Tension Test.
2. Run Tension Test.
3. Case setup for Torsion test.
4. Run Torsion test.
5. Evaluate results for listed parameters.

TENSION TEST:

• Open Ansys Workbench add Explicit dynamics to the window.
• Add material "Steel 1006" from the engineering data.

Co-Ordinate systems:

Create the co-ordinate systems as shown for both the faces of specimen.

Meshing:

• Insert the method and select the body and type as tetrahedrons.

• Insert the sizing select the one of the faces and type as the sphere of influence and sphere center as its co-ordinate system that we created and the element size as 3mm and sphere radius as 22mm.
• Do it for the both faces shown below with same criteria.

• Then generate mesh and the mesh on the specimen will be as shown below.

• Create the displacement under explicit dynamics and select the face as geometry.
• As the tension occurs in X-direction input the value of 18mm in the X-direction for the displacement.

• Create a fixed support such that the face is fixed during the simulation.

• Under the analysis setings enter the end time as 1e-3s.

• List the required outputs in the solution and click on solve.

Total deformation:

Equivalent Stress:

Equivalent Elastic Strain:

Temperature:

Displacement:8mm	Total Deformation(mm)	Equivalent Stress(MPa)	Equivalent Strain	Temperature (oC)
Tension Test	Max.18.007 Min.0	Max.612.67.204 Min.0.204	Max.0.0030 Min.3.2e-6	Max.270.96 Min.22

Torsion Test:

• Duplicate the tension test window, for the existing data and add new criteria required for the torsion test.
• Insert the co-ordinate system and select the type as cylindrical.
• Make sure the co-ordinate system directions were same as below.

• Insert sizing and select the faces as below and enter the element size as 1.5mm.

• Insert sizing select the face as below and type as sphere of influence and sphere type as global coordinate system.
• Enter the sphere radius as 8mm and element size as 1mm.

• Click on generate the mesh and the mesh will be generated with given criteria as below.

• Insert the displacement as 1200 degrees in the Y- direction and the others as 0.
• Set the co-ordinate system to cylindrical in the displacement tab.

• Now clear the previous generated results.
• Click on solve.

Total Deformation:

Equivalent Elastic Strain:

Temperature:

Displacement:1200 deg	Total Deformation(mm)	Equivalent Stress(MPa)	Equivalent Strain	Temperature (oC)
Torsion Test	Max.17.144 Min.0	Max.500.33 Min.0.099	Max.0.0030 Min.1.8e-6	Max.432.37 Min.22

Results: Thus the tension and torsion test has been performed on given work-piece using Ansys workbench.
