摘要 通过有限元的方法,分析了T型薄壁管节点受平面内弯矩作用下的疲劳行为,得到了应力最大值的位置和拟合出用于预测T型薄壁管节点受平面内弯矩作用下的应力集中系数的参数公式。 The fatigue behavior of welded thin-walled ding ,is analyzed by finite element. The corresponding and the proposed equations anticipating the SCF values obtained. T-joints, which is subjected to cyclic in-plane benlocations of the peak SCF values along the weld toe of the T-joints subjected to cyclic in-plane bendingis
