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
試件的整體斷裂為剪切型，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，說明局部較高的應力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剪切型斷裂模式；對韌性斷裂的剪切模式的細觀機理做了一定的探討，並且提出了含裂紋構件剪切型斷裂的宏觀判據：認為裂紋前方的集中剪切帶中與裂紋尖端等半徑處最大有效塑性應變出現的方向可以作為裂紋剪切斷裂的方向（可簡稱為_ （ pmax ）準則） ，集中剪切滑移帶貫穿裂紋前方承載韌帶時的載荷可以作為極限載荷；本文運用金屬韌性斷裂細觀力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。 -

In order to reduce the losses suffered from collision between passenger trains, a new design method for the car body structure of motor car and trailer is advanced. car body structures are made up of three parts with diffferen tstiffness, by carefully designed. the parts of the front and the end are the wea kstiffness structure to absorb energy through plastic deformation in the collision. the middle part, where only elastic deformation occurs, is an elastic deformati on structure with strong stiffness. as the passenger train runs normally, car body structure measure up to regulation of intensity and stiffness in the standards
為了減輕客運列車碰撞事故造成的損失，實現被動安全保護，對組成列車的動車、客車車體結構提出了新的設計方法，重新分配車體各部分剛度，設計出具有合適吸能結構的耐沖擊車體，車體結構均按前、中、后三種縱向剛度設置，前後兩部分為可以產生塑性變形的弱剛度吸能結構，中間部分為僅產生彈性變形的強剛度彈變結構。 -
