Dieter Exercise 8.18 Compare steels A and B for the construction of a pressure vessel 30 inch inside diameter and 12 feet long. The pressure vessel must withstand an internal pressure of 5000 psi. Design against a radial internal flaw of length 2a. Use a safety factor of 2. For each steel, determine [a] critical flaw size (yield before break) and [b] flaw size for a leak-before-break condition. Pressure vessel circumferential [hoop] stress,

Unformatted text preview: = Pd/2t where P = internal pressure, d = vessel diameter, t = wall thickness (allowed) = y /2; t = 5000*30/ y a cr related to plane strain fracture toughness, K 1c = [ a cr ] 1/2 not provided; assuming same for A and B [equals 1, a terrible assumption]. .. [a] a cr = [K 1c / a ] 2 / [b] for leak before break, 2a cr = t Steel A cannot be used in a leak before break application, steel B can. ......
