local stress concentration

基本解释

The results show that the branch pile can reduce the deformation of the upper structure, but may cause local stress concentration in the superstructure.
研究结果表明，支盘桩可以有效降低上部结构的变形，但可能在上部结构产生局部应力集中。
The fatigue life of different welding shapes between plates of unequal thickness in pressure vessel was investigated from the point of local stress concentration at welding position.
从焊接部位局部应力集中的角度分析了不等厚板在不同焊接形式下的疲劳寿命。
If the thin-wall pressure vessel is holed, it not only weakens material's strength of vessel, but also causes local stress concentration. That becomes one of important factors of destroyed vessels.
在薄壁压力容器器壁上开孔，不但削弱了容器的材料强度，而且导致容器局部应力集中，成为容器破坏的重要因素之一。
