normal stress

基本解释

The mode of the surface crack is open at beginning, that may be explained by the maximum normal stress theory.
结果表明，最初出现的表面裂纹是张开型的，其产生原因可以用最大拉应力理论来解释。
The objective is to verify the predictions of engineering beam theory in so far as that theory defines the centerline deflection and extreme values of the normal stress.
实验目的是证明现行的工程梁理论，这种理论定义了中心线变形和普通应力的极值。
The drawing test results show that the shear strength of the interface is not proportional to the normal stress because of its dilatancy behavior due to shear application.
土工布拉拔试验结果表明，由于土与土工织物接触面的剪胀造成该类接触面的抗剪强度与法向应力不再是线性关系；

Not only are they experiencing the normal stress of management but this imminent financial amputation is also pushing many to their limit.

正应力
The relationship between the shear strength of bonding layer and its normal stress was expatiated under low hydrostatic stress-state.
并从破坏机理上分析了影响粘结层剪切强度的因素；及对低静水应力状态下，粘结层剪切强度与其上作用的正应力关系进行了阐述。
正向应力

正应力
The normal stress in column increases gradually with depth above the neutral depth z m and decreases gradually with depth below the neutral depth z m, also decreases with replacement rate.
桩体正应力值在中性点以上随深度递增,中性点以下随深度递减,并且桩体正应力值随置换率的增加而减小。

法向应力
The results showed that the higher concentration is, the bigger first normal stress difference is. It means that solution has higher elastic energy.
聚丙烯酰胺溶液的浓度越高,聚合物溶液的第一法向应力差越大,说明聚合物溶液具有的弹性能量越高。
