摘要
采用有限元分析法和试验测定法,对平面闭合弯矩作用下外拱局部减薄弯管的极限载荷进行了研究,并由有限元计算结果数据拟合出外拱局部减薄弯管塑性极限弯矩的计算公式,该公式的计算结果与有限元计算结果、试验结果比较符合。
The plastic limit load of elbows with local thinned area in extrados under in-plane closing bending moment is discussed. Fnite element analysis （FEA） and experiments have been used. By data fitting of FEA, an empirical formula of the limit load for elbows with local thinned area in extrados has been attained. Limit load tests are carried out to validate the proposed formula.
