Week 9 Tension and Torsion test challenge

Objective

To perform a simple Tensile and Torsion Test on the Standard tensile test specimen and find out the following results by providing a displacement of 18mm in tensile test & a rotational twist of 1200°.

1. Total Deformation
2. Equivalent Stress
3. Temperature of the specimen

Case Setup

1. Material : Steel 1006 is applied to the specimen from the Ansys explicit materials library with flexible stiffness behavior.

2. Meshing: Specimen mesh element size is controlled using face sizing with a specific sphere of influence & element size.

3. Physical constraints or Boundary Conditions:

• Specimen is fixed at its one end by providing fixed support boundary condition.
• In Tensile Test, the other end of the specimen is given a axial displacement of 18 mm.
• In Torsion Test, specimen is rotated about its axial axis by providing rotation displacement of 1200°.

Results

Case1. TENSILE TEST

Equivalent Stress:                                                                                 Max. Equivalent Stress = 609.92MPa

Total Deformation:                                                                                       Max. Total Deformation = 18 mm

Temperature of the Specimen:                                                                    Max. Temperature = 265 degrees 

Case2. TORSION TEST

Equivalent Stress:                                                                                 Max. Equivalent Stress = 572.4 MPa

Total Deformation:                                                                                Max. Total Deformation = 10.433 mm

Temperature of the Specimen:                                                               Max. Temperature = 440.97 degrees

Summary

Results of both the cases shows that the boundary condition is well executed in the simulation i.e. In tensile test body is displaced by 18 mm & in Torsion test specified rotation is achieved. Equivalent stress results shows the reiteration of standardized practical results of Tensile and Torsion test. While Temperature of the specimen shows the expected results, as the portion where the most yielding occurs resulted in highest temperature points.
