- The following conclusions are gained : ( 1 ) the located shear band prongs the ligament near the top crack tip and the structure may occur shear - mode fracture at the angle of 155 ? to crack when load is 87 . 92mpa ; the mode of fracture of the flange joint structure is not possible to be void - mode ; ( 2 ) it is proved that loading and then unloading repeatedly can not increase the possibility of invalidation of the structure when the times of loading and unloading are not too more when load is operating pressure ; the structure is safe when the vessel is operating ; ( 3 ) in the fe model of the thesis , not considering the influence of water pressure test which is in the process of fabrication of vessel in fe results in larger deviation in analysi
得出了以下结论：在8792mpa的载荷下筒体一封头连接结构处的集中剪切带贯穿韧带，可能发生沿与原裂纹线成155 “角方向剪切型断裂；筒体一封头连接结构不可能发生韧窝型断裂； （ 2 ）在工作压力下进行次数不多的反复加、卸载，结构不会破坏，也不会丧失安定性：结构在工作状态下是安全的； m在本文的弹塑性有限元模拟计算中，对于裂纹尖端进行力学分析时，不考虑压力容器制造过程中水压试验的影响，将导致计算结果出现较大的偏差； （ 4 ）筒体完全屈服时的载荷为92石3mpa ，封头完全屈服时载荷为86
