摘　　要：针对压力容器接管区高峰应变的特征 ,在压力容器接管模拟试板的基础上 ,对多种孔径的异型板应力应变场建立有限元模型 ,分别就不带裂纹和带有裂纹的异型板进行应力分析。计算结果表明高峰应变区的应力集中与试验结果较为吻合 ,为异型板设计的合理性和裂纹扩展分析提供了可靠依据。According to high strain gradients characteristic at the junction between pressure vessel and nozzle,based on simulating shape plate of pressure vessel nozzle,FEM's models are established for two types of special shape plates.The stresses are obtained by means of finite element method.The calculating results are accord with those of experiment results.This paper provides the foundation for designing of special shape plates and analysis of extending crack.
