中文拼音 [jǐhúxiàn]
脊弧線
英文
sheer curve at center-
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。Bainianyuan bed selects high quality environment - materials, utilizes most advanced manufacturing techniques. thmattress has carefully sdldcted materials to achieve perfect cont contac with human body, and let you enjoy most relaxing and comfortable sleep
百年緣選用高品質環保材料，利用尖端生產工藝精緻成，床墊墊料都經過特別挑選，能緊貼人體曲線，讓每一點均勻承托您的背脊而又可保持背脊的原理弧度，令您享有最輕松舒適的睡眠感覺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。分享友人
