OBJECTIVES

For this challenge, you will have to perform the tension and torsion test on the specimen provided below the video corresponding to the challenge.

For the tension test, displace one end of the specimen to 18mm while keeping the other fixed. You will need to find out the total deformation, equivalent stress and temperature of the specimen and attach appropriate images to show your results.

For the torsion test, you will need to displace one end of the specimen to an angle of 1200 degree. Find out the total deformation, equivalent stress and temperature of the specimen and attach images to show your results.

3.5 SOLUTIONS

	TENSION TEST
	CASE - 1	CASE - 2	COMPARISON
Total deformation			Found total deformation same as the displacement load applied.
Equivalent stress			As the sample is plastically deformed, there is not significant difference between case 1 and 2 with respect to the difference in displacement load application.
Temperature of the specimen			As the displacement load is more in case 2, temperature developed is also more in case 2.
	TORSION TEST
	CASE - 1	CASE - 2	COMPARISON
Total deformation			Total deformation found for the dust particles produced
Equivalent stress			As the sample is plastically deformed, there is not significant difference between case 1 and 2 with respect to the difference in displacement load application.
Temperature of the specimen			As the displacement load is more in case 2, temperature developed is also more in case 2.

• CONCLUSSION

Simulation of Tension and Torsion Test of Steel 1006 material conducted with Ansys Workbench. From the analysis it is found that when the displacement load increases, temperature developed is high. Both cases it is found that, after plastic deformation, there is no significant change in stress developed.
