| 摘 要： | 本文用动力松弛法(DRM)求解了两层正交铺设双模量叠层方板在三种边界条件下的非线性弯曲问题。文中对DRM的阻尼系数的确定方法作了改进;指出了使用Bert模型计算各点的刚度时应考虑该点曲率的各种组合情况;给出了受正弦载荷和均布载荷作用的两种双模量复合材料叠层板的数值结果,得出了一些有用的结论。

| Abstract: | In this paper,Dynamic-Relaxation Method(DRM)has been adopted to investigate the problem of nonlinear bending of two- layer cross-ply square plates laminated of bimodular composite materials for three types of boundary condition.In the present paper the approach of estimating damping factor for DRM has been improved and it is indicated that various combinatorial cases of the curvature of each nodal point must be considered in using the Bert modal for calculating stiffness of the nodal point.The numeri- cal results are given for the plates laminated of two kinds of bimodular composite materials under sinusoidally distributed or uniformly distributed transverse loads and some useful conclusions are reached. |
