Experimental Validation of the Evaluation of Reinforced Openings in Large Steel Pressure Vessels 大型钢制压力容器补强开孔评估的实验验证
本文介绍了一个装在一个非常小的喷管上的大型、非常薄的容器的实验技术和结果。这些结果以及其他结果表明,对于这些类型的血管,分析结果可能会高估无量纲应力结果,高达约三倍。当容器的厚度不比喷嘴的厚度大或小得多时,非常薄的大型容器的应力结果似乎与喷嘴的厚度无关。对于这些类型的容器,每个应力结果的实验数据都可以线性化,这种线性化大大减少了图表的数量。
Experimental techniques and results of a large, very thin vessel loaded on a very small nozzle are represented. These results, as well as others, indicate that analytical results can overestimate nondimensional stress resultants up to a factor of about three for these types of vessels. Stress resultants of large, very thin vessels appear to be independent of the nozzle thickness, when the thickness of the vessel is not much larger or smaller than that of the nozzle. For these types of vessels experimental data may be linearized for each stress resultant, and this linearization greatly reduces the number of diagrams.
