Week 9 Tension and Torsion test challenge

OBJECTIVE 

To perform the tension and torsion test on the specimen

For the Tension Test dipslace one end of the specimen to 18mm while keeping the other fixed

For the Torsion Test displace one end  of the specimen to an angle of 1200 degree while keeping teh other fixed 

Find out the total defomation equivalent stress and tempertaure of the specimen

 PRODECURE

Tension Test 

Create Explicit Dynamics in Ansys workbench and in engineering data select the material steel 1006 from explicit materials 

Steel 1006

Import the geometry and check in Spaceclaim for any irregularties

Then open Ansys mechanical and assign the steel 1006 and material to the components 

                                                            

Coordinate System  For meshing two additional carestian system are defined

                                                           

Mesh   The model is meshed by using Patch conforming method and tetrahedrons used.

Face sizing   Face sizing option used .Type set to sphere of influence with sphere center as the center of the manually defined coordinate system and sphere  radius of 22mm and element size of 3mm

                           

                                                     

Final Mesh 

          

Analysis Setting   Set end time as 1e-3 and all the setting set to default

Fixed Support    One end of the specimen is fixed

                                                   

Displacement    Displace other end of the specimen to 18mm

                                                   

Result      The analysis runs successfully and results obtained

Total Deformation Max - 18.004mm

                                                    

                                                    

Equivalent Stress Max - 610.15 Mpa

                                              

                                               

Temperature Max - 266.76 Degree Celsius

                                                       

                                                       

Conclusion 

• Max equivalent stress is developed in the center portion of the workpiece where neck formation occurs
• Maximum Temperature is developed at the center portion
• The maximum deformation of the workpiece is 18.004 which matches the given displacement value

Torsion Test 

Create Explicit Dynamics in Ansys worrkbench and in engineering data select the material steel 1006 from explicit material 

Steel 1006

Import the geometry and check in spaceclaim for any irregularties

Then open Ansys Mechanical and assign the steel 1006 material to the components 

                                                     

Coordinate System   For meshing two additional carestian coordinate system are defined and one cylindrical coordinates defined

                                                 

Mesh   The model is  meshed by using batch conforming method and tetrahedrons used.

Face Sizing   Face Sizing option used Type set to sphere of influence with sphere center as the center of the manually defined coordinate system and sphere radius of 22mm and element size of 3mm

                                                     

Face Sizing   2Face of the specimen in meshed with element size of 1.5mm

                                                 

Face Sizing Type set to sphere of influence with sphere center as the center of the manually defined system and sphere radius of 8mm and element size of 1mm

                                                  

Final Mesh

                                                                

Analysis Setting  Set endtime as 1e-3 and all the the setting set to default

Fixed Support   One end of the specimen is fixed

                                                    

Displacement   Displace one end of the specimen to an angle of 1200 degree

                                                 

Run the simulation and results obtained

Result The analysis runs successfully and results obtained

Total Deformation Max - 13.241mm

                                             

                                           

Equivalent Stress Max - 566.72 Mpa

                                         

                                         

Temperature Max - 455.52 Degree Celsius

                                               

                                                

CONCLUSION 

• Max equivalent stress is developed in the center portion of the workpiece 
• Maximum Temperature is developed at the center position
