内压容器的边缘应力及其对容器封头焊缝的影响

内压容器的边缘应力具有局部性及自限性的特点 ,它是压缩变形产生的 ,可用微分方程来分析计算。在实际设计内压容器时 ,应充分考虑封头的形状对边缘应力的影响 ,从而设计出安全可靠的内压容器。

Fringe Stress of Container with Internal Compression and Its Impact on Welding Seam of Sealed Crack in Container

Limitations and self limitations characterize fringe stress of container with internal compres sion, which is caused by compressive deformation and can be analysed and calculated byapplying differen tial equation. While designing a container with internal compression, we ought to take the shape of sealed crack and its impact on fringe stress into full consideration so as to design a safe and durable container with internal compression.
