| 5. | The accomplishing method is that the attack angles of aerodynamic forces are made changing along transmission line so aerodynamic forces are made being approximate balance state by spiral winding plastic belt on transmission line
实现的方法是在输电线螺旋地缠绕横截面为三角形的塑料带，使气动力的攻角沿输电线的长度方向周期性地变化，使作用在输电线上的气动力近似地成为平衡力系。 |
| 6. | Still , the change of vg parameter in the beam was investigated in this thesis . dilation of plastic belt in the beam is also studied . analysis show that there is clear direction during the dilation of plastic belt , which is similar with the path of shear - mode fracture
分析表明塑性区的扩展有明显方向性，据此得到的塑性区扩展方向与剪切型断裂时的断裂路径比较接近，也与加载过程中韧带区出现的集中剪切滑移线的方向比较一致。 |
| 7. | 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。 |
