摘要
本文将管接头的半解析变分解法和有限元法相结合,计算了Y型接头的焊缝及焊缝附近区域的应力,并给出了凹型焊缝应力分布.文中提出的计算方法较之过去焊缝分析中所用的三维有限元模型及二维、三维有限元组合模型,具有节省计算量和计算机内存等优点.
The computation of stress distribution in the regions of the weld
of tubular Y-joints and its neighborhood by combining the method of varia-
tional prinoiples and that of the finite element analysis.The numerical
computation of the stress distribution in the concave weld is presented in
this paper.The merits of this method in core memory saving and computa-
tional time saving as compared with the combined method of two-and three-
dimension finite element analysis are discussed.
