local stress concentration

基本解釋

The results show that the branch pile can reduce the deformation of the upper structure, but may cause local stress concentration in the superstructure.
研究結(jié)果表明，支盤(pán)樁可以有效降低上部結(jié)構(gòu)的變形，但可能在上部結(jié)構(gòu)產(chǎn)生局部應(yīng)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.
從焊接部位局部應(yīng)力集中的角度分析了不等厚板在不同焊接形式下的疲勞壽命。
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.
在薄壁壓力容器器壁上開(kāi)孔，不但削弱了容器的材料強(qiáng)度，而且導(dǎo)致容器局部應(yīng)力集中，成為容器破壞的重要因素之一。
