摘要
介绍了压力容器分析设计中塑性分析方法的有限元数值模型,对圆柱壳径向开孔接管结构进行了塑性分析,并将分析得到的塑性垮塌载荷与实验得到的爆破压力进行了对比,为压力容器塑性分析方法的工程应用提供一定的参考。
In this article, the plastic analysis for opening structure of normal nozzle on cylindrical shell was carried out by using finite element method. The rupture load resulted from the analysis was compared with the explosion pressure in experiment. The result of comparison may be referenced in use of plastic analysis in engineering.
