摘要
本文给出了用三维有限元计算球面凹坑应力场所得到的结果。通过分析有限元计算结果,利用其差商关系确定了凹坑处应力场的工程算法,为进一步理论分析及计算提供了方便。
Results of finite element analysis of stress on concave-down defects in pressure vessel were given in this paper. Stress function used in concave-down has been constructed with results of finite element analysis. Results computed with stress function conforms to test results on pressure vessel.
