Find the safety factor when considering crack propagation


A pressure vessel made of aluminum alloy 2024?T351 (Sy = 325 MPa and Kc = 36 MPa?m1/2) is manufactured for a safety factor of 2.5 considering yielding. However, the material contains cracks through the wall thickness with a crack half?length less than 3 mm. Find the safety factor when considering crack propagation. Assume that the geometric factor ß = 1.
