根据试验和非限性有限元方法 ,在逐渐增加内压荷载下 ,为壳体与接管直径比为d/D =0 5 2 6的容器接管截面提供了非弹性应力分析结果。为了与有限元分析进行对比 ,借助试验确定因内压而导致的极限荷载。提供了模拟容器分析所需的塑性区扩展范围。另外 ,还对模拟容器进行了破裂试验 ,为内压加载情况下的壳体断面提供了数据 ,来证明现用的设计方法是正确的 ,并为开发新的设计规范奠定了基础 According to the experimental and non-finite element method, the non-elastic stress analysis results are provided for the tube cross-section of the container with the shell diameter d = 0 5 2 6 under the condition of increasing internal pressure. In order to compare with the finite element analysis, the limit load caused by the internal pressure is determined through experiments. Provides the plastic zone extension required to model container analysis. In addition, the rupture test was also performed on the simulated container, providing data for the shell section under internal pressure loading to demonstrate that the design method used was correct and laid the groundwork for the development of new design specifications
