The aim of this study was to establish the effect of cross bore configuration geometry on stress concentration in cross-bored high-pressure vessels. The cross bore geometry parameters with adverse effects on stress concentration include cross bore size, shape, location, obliquity, and thickness ratio. However, there were no conducted studies on the optimal combination on these geometric configuration parameters that give minimum stress concentration, although the cited phenomena are common in pressure vessel design. Therefore, there is need for further research on the optimal geometric configuration in a high-pressure vessel under elastic, elastoplastic, and plastic operating conditions with regards to the selected cross bore configuration parameters. Optimization of the stress concentration factor will greatly improve the design of high-pressure vessels.

跨孔几何形状配置对高压容器中应力集中的影响：综述

这项研究的目的是确定横孔构造几何形状对横孔高压容器中应力集中的影响。对应力集中有不利影响的过孔几何参数包括过孔尺寸，形状，位置，倾斜度和厚度比。但是，尽管所提及的现象在压力容器设计中很常见，但尚未对这些给出最小应力集中的几何构型参数进行最佳组合的研究。因此，需要针对选定的横孔构型参数，进一步研究在弹性，弹塑性和塑性操作条件下的高压容器中的最佳几何构型。
