| 摘 要： | 基于正交异性板理论,将双向正交密加筋板进行构造正交异性和物理正交异性的等效转换.采用数值分析方法,对一系列单轴受压的双向正交密加筋板进行了有限元非线性计算.基于有限元数值计算结果和正交异性板理论,提出了双向正交密加筋板的极限强度预报公式.比较结果表明,提出的公式更为简便、合理,可以准确对双向正交密加筋板的极限强度进行预报.

| Abstract: | Based on the orthotropic plate theory,this paper described geometrical configuration and material orthotropic equivalent conversion for the two-way orthogonal multi-stiffened plates.Nonlinear FEM has been performed to a series of two-way orthogonal multi-stiffened plates subjected to axial compression load.Based on the numerical results and orthotropic plate theory,a proposed formula is presented for the ultimate strength prediction of two-way orthogonal multi-stiffened plates.Comparison results show that the simple and reasonable formula can forecast the ultimate strength of the twoway orthogonal multi-stiffened plates more accurately. |
