压力容器焊缝角变形应力集中的数值分析方法

A Numerical Analysis Method of Stress Concentration for the Angular Distortion of Weld in Pressure Vessel

本文通过对计算模型用FEM BEM结合法进行计算与分析,其计算结果与理论值具有良好的一致性。FEM—BEM结合法充分发挥了FEM法和BEM法各自的优点,可以用于工程上评价存在角变形压力容器的可靠性。

By the calculation and analysis of the caculation model combined with the FEM-BEM, caculation results is uniform with the theoretical values. The combination method is fully display the excellents. It can'be used to evaluate the engineering reliality of angular distortion pressure vessels.
