摘要
利用MSC/Patran and MSC/Nastran对焊接中常见的对接接头焊趾处的应力集中系数进行有限元建模和计算,在分析有限元计算结果的基础上,提出比较完整的估算焊接接头应力集中系数公式。
The FE analysis for the stress concentration factors of the common welded joints was carried out in MSC/Patran and MSC/Nastran.A set of new and completed empirical formulas for evaluating the stress concentration factors at welded joints was regressed based on the numerical results of FEA.
