In short, the analysis of arc - tip fracture shows that : the initiation of void - mode fracture can be judged by vgc criterion, or by j ". according to sx criterion ; fracture direction of void - mode fracture can be determined by ctod and peak value line of stress triaxiality. the mesomechanics mechanism of shear - mode fracture need further study, and analysis found direction of plastic belt is consistent with the direction of shear - mode fracture
綜上所述,本文通過對圓弧尖端裂紋的分析表明:對于韌窩型斷裂的起裂,可以依據-復合型斷裂的sx準則按照i ~ 1來預測起裂載荷,也可用v _ ( gc )判據來預測起裂載荷,二者結果相近;對于韌窩型斷裂的斷裂角,用ctod矢量方向和三軸度脊線方向判斷均和試驗結果基本。 -
The thesis studied the change of stress triaxiality in the four - point curved beam made in 16mnr with arc - tip crack and its important effect. in the beam, the points of peak value of stress triaxiality distribute along a line, whose direction is well consistent with the fracture direction got by experiment when so > 3mm
在圓弧裂紋試件中,裂尖附近的三軸度較高的點呈脊線分佈,按照脊線分佈擬合計算得到的三軸度脊線夾角在偏心距so 3mm時與試驗測得的斷裂角符合較好,這種情況下試件發生的是韌窩型斷裂。 -
