| Abstract: | 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. |
