摘要:
采用断裂力学中的最大周向应力理论,通过分析带有裂纹的薄壁圆筒压力容器在受所储气体或液体的内压力p作用下的应力状态,研究裂纹尖端形成的复合型应力,推导出裂纹开始扩展临界状态时的开裂角θ0,得出裂纹角β与开裂角θ0的关系,并推导出临界荷载pcr。最后将所得结果与现行钢制压力容器规范的结果比较,表明现行钢制压力容器规范的结果实用、安全。
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.
