摘要

采用非线性有限元法进行了一系列有限元分析，研究了边界条件和模型范围对极限强度和膨胀行为的影响。采用相同截面尺寸、不同加筋数的模型，研究了模型扩展的影响和模型可移植程度的选择。另一组具有相同截面尺寸和范围的模型采用了不同的边界条件，包括简支边界条件、固支边界条件和周期边界条件。研究了不同几何模型和边界条件下加筋板的连续性对其破坏模式的影响。

Influence of FE modeling on ultimate strength of Y-shape stiffened panels under axial compression

A series of FE analyses are conducted to investigate the influence of boundary conditions and model range on the ultimate strength and bulking behavior with Non-linear FE (finite element) method. Models that have same section size and include different number of stiffeners are used in research about influence of extent of model and choosing a portable extent of model. Another set of models with same section size and extent are applied different boundary conditions including simply supported boundary, clamped supported boundary condition and periodical boundary condition. The effects of the continuity of the stiffened panel with different geometric models and boundary conditions on its collapse mode are investigated.
