  1. Author thinks that the direction of the maximum plastic distortion along a constant radius around the crack tip may be considered as the direction of shear - mode fracture ( named pmax - criterion ) and the load when located shear band prongs the ligament in the front of crack tip is regarded as the limited load of shear - mode fracture. ( 3 ) the fad ( fracture assessment diagram ) of titled crack is proposed based on achievements of mesomechanics about i - ii complex ductile fracture of metal, and the titled crack is classified two kinds : void - mode fracture is assessed by fracture assessment curve, and shear - mode fracture by limited load. ( 4 ) using a fe program based on plantle - ressue theory to calculate some mesomechanical parameters, a flange joint structure of a high pressure vessel ( design pressure 31. 4mpa and the thickness of the hemispherical head is half of that of shell. ) is analyzed to determine whether the structure under operation pressure is safe or not, forecast the mode of potential invalidation and argue for the rationality of design of the structure

    試件的整體斷裂為型,但在試件芯部裂尖鈍化區中部出現了韌窩型啟裂並有一定的擴展,說明局部較高的三軸度也會使韌窩型機制得以發展,但是不改變試件整體的型斷裂模式;對韌性斷裂的模式的細觀機理做了一定的探討,並且提出了含裂紋構件型斷裂的宏觀判據:認為裂紋前方的集中帶中與裂紋尖端等半徑處最大有效塑性變出現的方向可以作為裂紋斷裂的方向(可簡稱為_ ( pmax )準則) ,集中滑移帶貫穿裂紋前方承載韌帶時的載荷可以作為載荷;本文運用金屬韌性斷裂細觀學在一復合型韌性斷裂方面的研究成果,採用失效評定圖的形式,提出了傾斜裂紋的安全性評定方法的基本框架。
