fracture angle meaning in Chinese

破坏角
破环角

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。
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。
