Abstract:
Based on the theory of maximum circumferential stress of fracture mechanics, and by analyzing the stress of the thin-walled cylinder pressure vessel with crack which was under the action of pressure p(generated by the gas or liquid inside), authors studied the mixed mode crack stress; acquired the cracking angle θ0 when the crack began to expand; obtained the relation of cracking angle θ0 and crack initiation angle β, and deduced critical loads pcr. Finally, by comparing the result of this paper with active criterion on steel pressure vessels, authors concluded that active criterion on steel pressure vessels is practical and in safe range.
