| Cases | Material | Friction Coefficient | Directional Deformation (mm) | Equivalent Elastic Strain (mm/mm) | Equivalent Stress (MPa) | |||
| Maximum | Minimum | Maximum | Minimum | Maximum | Minimum | |||
| Case 1 | Aluminum Alloy 1199 | 0.1 | 2.3453 | -12.433 | 0.0015718 | 1.226×10^-13 | 62.573 | 2.4519×10^-8 |
| Copper Alloy NL | 0.1 | 2.7977 | -11.655 | 0.0017309 | 1.1018×10^-12 | 135.33 | 2.2001×10^-7 | |
| Magnesium Alloy NL | 0.1 | 2.536 | -11.338 | 0.0027907 | 1.0219×10^-12 | 89.014 | 2.0436×10^-7 | |
| Case 2 | Aluminum Alloy 1199 | 0.19 | 2.3219 | -12.387 | 0.0015928 | 1.1711×10^-13 | 59.559 | 2.3422×10^-8 |
| Case 3 | Aluminum Alloy 1199 | 0.1 | 2.3757 | -12.355 | 0.0016608 | 7.6484×10^-14 | 82.652 | 1.5292×10^-8 |
Conclusion: The directional deformation and stress are maximum for Copper Alloy NL, lesser for Magnesium Alloy NL and least for Aluminum Alloy 1199. Strain is maximum for Magnesium Alloy NL, lesser for Copper Alloy NL and least for Aluminum Alloy 1199. As friction coefficient increases, the directional deformation and stress decrease whereas strain increases. Thus, the Young's Modulus of the material plays an important role in it.
