| Abstract: | Based on elsto-plastic mechanical model and the Von-Mises collapse criterion, the authors analyze the welded hollow spherical joints with different form of costalia. In this paper, nonlinear finite element analysis on the welded hollow spherical joints is carried out. The effect of various geometric parameters of the joints on its behavior and ultimate compressive capacity is investigated theoretically. Through a lot of calculation and analysis some useful conclusion is presented. |
