| Abstract: | This paper mainly do the calculation and research on the ultimate strength of panels and stiffened-plates under combined bi-axial compressions and lateral pressure based on nonlinear FEM.It focused on the applying of the initial imperfection of the plate and stiffened-plate,and also on discussing the element size,boundary condition,multi-load step for nonlinear FEM solution.The paper has carried out the ultimate strength calculation for a panel and a stiffened-plate under various combined bi-axial compression and lateral pressure.It is showed that the procedures taken in this paper is correct and effective,and the results are agreed well with other references. |
