vgc meaning in Chinese
粘度比重常数
Examples
- Vgc standard test method for calculation of viscosity - gravity constant of petroleum oils
石油润滑油粘度-重力常数 - One is void - model fracture which is resulted from initial , dilatation and coalescence of voids in material . the fracture criterion of void - model fracture is vgc - criterion or ctodi - criterion , and its fracture angle is able to be determined by m - criterion
韧窝型断裂由材料内空穴的形核、扩张和汇合造成，断裂判据可以采用“ v _ ( gc )准则”或ctod ~ i准则，断裂角可以采用m准则确定。 - 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
综上所述，本文通过对圆弧尖端裂纹的分析表明：对于韧窝型断裂的起裂，可以依据-复合型断裂的sx准则按照i ~ 1来预测起裂载荷，也可用v _ ( gc )判据来预测起裂载荷，二者结果相近；对于韧窝型断裂的断裂角，用ctod矢量方向和三轴度脊线方向判断均和试验结果基本。 - 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
对裂纹尖端张开位移ctod及其张开型分量~ 1和剪切型分量~ 11的分析表明，在试件发生韧窝型断裂时，按照圆弧裂纹中ctod矢量的垂直方向预测的断裂角与试验测得的断裂角符合较好，与三轴度脊线预计的结果也比较一致。
