  2. 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

    得出了以下結論:在8792mpa的載荷下筒體一封頭連接結構處的集中剪切帶貫穿韌帶,可能發生沿與原裂紋線成155 「角方向剪切型斷裂;筒體一封頭連接結構不可能發生韌窩型斷裂; ( 2 )在工作壓力下進行次數不多的反復加、卸載,結構不會破壞,也不會喪失安定性:結構在工作態下是安全的; m在本文的彈塑性有限元模擬計算中,對于裂紋端進行力學分析時,不考慮壓力容製造過程中水壓試驗的影響,將導致計算結果出現較大的偏差; ( 4 )筒體完全屈服時的載荷為923mpa ,封頭完全屈服時載荷為86
