軸向脊線 的英文怎麼說
中文拼音 [zhóuxiàngjǐxiàn]
軸向脊線
英文
axial hinge line-
Research about ctod and its components 8 ", " shows that the direction angle of ctod vector is identical with the fracture angle of void - mode fracture, which is obtained through experiments, and it is also identical with the result got by peak value line of stress triaxiality. besides, 8 i " was compare with vgc as criterion for initiation of void - mode fracture
對裂紋尖端張開位移ctod及其張開型分量~ 1和剪切型分量~ 11的分析表明,在試件發生韌窩型斷裂時,按照圓弧裂紋中ctod矢量的垂直方向預測的斷裂角與試驗測得的斷裂角符合較好,與三軸度脊線預計的結果也比較一致。Axial hinge line
軸向脊線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。
