| Abstract: | The plate buckling is analyzed by Patran and MSC Nastran. The buckling calculation method by finite element is determined, and the effect of the aspect ratio and thickness of plate on grillage structure buckling performance is obtained. The critical compressive stress formula for plate which afforded 4 sides compressive stresses is deduced and verified by finite element method. |
