A cylindrical pressure vessel has an inner diameter of 200 mm and a wall thickness of 5.00 mm, and it contains a pressure of 16.0 MPa. The safety factor against yielding must be at least X = 2.50. Also, a leak-before-break criterion must be met, with a safety factor of at least Xa = 11.0 on crack length, requiring Cc 2 Xat. (a) If the vessel is made from 300-M steel (300°C temper), calculate the safety factor on crack length and the safety factor against yielding (Hint: employ the Octahedral Shear Stress yield criterion) According to these results, is the vessel safe? (b) If the vessel is made from ASTM A517-F steel, indicate the safety factor on crack length and the safety factor against yielding (Hint: employ the Octahedral Shear Stress yield criterion) Is the vessel safe? (c) What minimum fracture toughness is required for the material in this application? (Enter result in MPa/m) (d) What is the safety factor on K relative to Kic due to the Xa = 11.0 requirement?
