Results and Conclusion:
| Contact Behaviour | Total Deformation (mm) | Stress (MPa) | Strain mm/mm |
| Frictionless | 50.8 | 2674.7 | 0.013 |
| Friction - 0.1 | 50.8 | 2888.6 | 0.014 |
| Friction - 0.2 | 50.8 | 3534.5 | 0.017 |
After observing the results we can conclude from this experiment that as the frictional value increases the value of stress also increasing.
