极限载荷分析方法的实践与讨论

Practicality and Discussion of Limit Load Analysis Method

我国现行分析设计标准采用第三强度理论,基于此前提,在压力容器设计过程中,采用极限载荷分析时会遇到一些问题。就设计计算过程中遇到的一些问题进行阐述,提出了实际建议。重点讨论了采用等效Mises屈服极限方法的适用性。

In current Chinese analysis design standard for pressure vessel,the third strength theory is applied.In design of pressure vessel on this basis,there are problems encountered in limit analysis for loads.In this article,some problems occurred in the procedure of calculation were described,and then some practical suggestions were presented.Emphatically,the adaptability of equivalent Mises yielding criterion was discussed.
