In addition, the crack position and configuration reflect the direction and centralized position of the pull stress in concrete, which is certainly corresponding with the reason of the way producting pull stress.
另外,裂缝的位置和形态近似反映了混凝土内拉应力的方向和集中部位,与产生拉应力的原因之间存在比较确定的对应关系。

General design requirements are not only a drag stress or a small pull stress.
一般设计中均要求不出现拉应力或者只出现很小的拉应力。
The radial stress is press stress in the joint axis and is gradually from press stress chang into pull stress in the area further away from the axis.
接头内径向残余应力在轴心处为压应力，随着远离轴心逐渐由拉应力变为压应力，在接头边缘区域为拉应力。
The maximum cutting stress lie of the radial distance of 0.5 double diameter nozzle, while the maximum pull stress lie in the surface edge of the rock.
岩石破坏时最大剪应力位于0.5倍喷嘴直径的径向距离处，同时在固体介质表面边缘产生最大拉应力。
