Based on lots of experiments, by combining the progress in mesomechanics with fea computation and analysis, this thesis investigated many parameters " effect on crack with an arc - tip in plain mixed - mode fracture, and compared existing criteria for fracture initiation, fracture direction and fracture mode transition
本文主要的工作是在試驗的基礎上，結合細觀斷裂力學當前的研究進展，通過有限元計算和模擬分析，研究了平面復合型斷裂中各種力學參量對圓弧尖端裂紋斷裂的影響，比較分析了現有的起裂判據、斷裂擴展方向的判定方法以及斷裂模式的轉換條件。 -
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。 -
