A spherical pressure vessel has adiameterof1.2 m and a wall thicknessof5 mm. The material is made ofsteel with fracture toughness 100MPa·m1/2, and σY= 1200 MPa. Assume that any crack that forms is elliptical in shape, with a surface trace of 2aand depth 0.5a, and that for this configuration, KI = σπ푎. What is the maximum pressure that the cylinder can experience before failure occurs? Use the leak-before-break criterion for fracture considerations. (9.4MPa)
