Three aluminium cylindrical pressure vessels thicknesses 14 mm and radius 840 mm. They are periodically filled and emptied to an interal pressure of 2MPa. Cracks can grow through the wall driven by cycle of stress on pressurisation.

Yield Stress (MPa) Fracture Toughness (MPa.m^.5)

Al 2024 300 40

Al 6061 110 35

Al 5454 140 20

Determine the failure mode of each vessel: yield / leak / fracture. Comment on which material would be best for this application.
