CONCLUSION :
|
Equivalent Stress (MPa) |
Total Deformation (mm) |
Stress Intensity (MPa) | |
| Cast Iron | 348.3 | 30 | 364.16 |
| Cast Steel | 350.2 | 30 | 368.04 |
| Cast Bronze | 342.7 | 30 | 363.54 |
Stress Intensity factor for Cast Bronze is less so chances of fracture is less also Stress is less in this case comparing with others .
I will recommend Cast Bronze on the basis of these results .
