Week 9 Tension and Torsion test challenge
Aim : To perform explicit dynamic analysis on the tension and torsion test model.
Objectives :
- Tension Test : 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.
- Torsion Test : 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.
